class DataFrame(BasePandasDataset):
    """
    Snowpark pandas representation of ``pandas.DataFrame`` with a lazily-evaluated relational dataset.

    A DataFrame is considered lazy because it encapsulates the computation or query required to produce
    the final dataset. The computation is not performed until the datasets need to be displayed, or I/O
    methods like to_pandas, to_snowflake are called.

    Internally, the underlying data are stored as Snowflake table with rows and columns.

    Parameters
    ----------
    data : DataFrame, Series, `pandas.DataFrame <https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.html>`_, ndarray, Iterable or dict, optional
        Dict can contain ``Series``, arrays, constants, dataclass or list-like objects.
        If data is a dict, column order follows insertion-order.
    index : Index or array-like, optional
        Index to use for resulting frame. Will default to ``RangeIndex`` if no
        indexing information part of input data and no index provided.
    columns : Index or array-like, optional
        Column labels to use for resulting frame. Will default to
        ``RangeIndex`` if no column labels are provided.
    dtype : str, np.dtype, or pandas.ExtensionDtype, optional
        Data type to force. Only a single dtype is allowed. If None, infer.
    copy : bool, default: False
        Copy data from inputs. Only affects ``pandas.DataFrame`` / 2d ndarray input.
    query_compiler : BaseQueryCompiler, optional
        A query compiler object to create the ``DataFrame`` from.

    Notes
    -----
    ``DataFrame`` can be created either from passed `data` or `query_compiler`. If both
    parameters are provided, an assertion error will be raised. `query_compiler` can only
    be specified when the `data`, `index`, and `columns` are None.

    Using pandas/NumPy/Python data structures as the `data` parameter is less desirable since
    importing such data structures is very inefficient.
    Please use previously created Modin structures or import data using highly efficient Modin IO
    tools (for example ``pd.read_csv``).

    Examples
    --------
    Creating a Snowpark pandas DataFrame from a dictionary:

    ...                 dtype=[("a", "i4"), ("b", "i4"), ("c", "i4")])
    >>> df3 = pd.DataFrame(data, columns=['c', 'a'])
    ...
    >>> df3
       c  a
    0  3  1
    1  6  4
    2  9  7

        Return the dtypes in the ``DataFrame``.
        This returns a Series with the data type of each column.
        The result's index is the original DataFrame's columns. Columns

        The returned dtype for each label is the 'largest' numpy type for the

        For labels with integer-type data, int64 is returned.

        For floating point and decimal data, float64 is returned.

        Apply a function to a Dataframe elementwise.

        This method applies a function that accepts and returns a scalar
        to every element of a DataFrame.

        Parameters
        ----------
        func : callable
            Python function, returns a single value from a single value.
        na_action : {None, 'ignore'}, default None
            If ‘ignore’, propagate NaN values, without passing them to func.
        **kwargs
            Additional keyword arguments to pass as keywords arguments to
            `func`.

        Returns
        -------
        DataFrame
            Transformed DataFrame.

        1  5  5

        When you use the applymap function, a user-defined function (UDF) is generated and
        applied to each column. However, in many cases, you can achieve the same results
        more efficiently by utilizing alternative dataframe operations instead of applymap.
        For example, You could square each number elementwise.

        >>> df.applymap(lambda x: x**2)

        1  11.262736  20.857489

        But it's better to avoid applymap in that case.

        Apply a function along an axis of the DataFrame.

        Objects passed to the function are Series objects whose index is
        either the DataFrame's index (``axis=0``) or the DataFrame's columns
        (``axis=1``). By default (``result_type=None``), the final return type
        is inferred from the return type of the applied function. Otherwise,
        it depends on the `result_type` argument.

        Snowpark pandas currently only supports ``apply`` with ``axis=1`` and callable ``func``.

        Parameters
        ----------
        func : function
            A Python function object to apply to each column or row.

        axis : {0 or 'index', 1 or 'columns'}, default 0
            Axis along which the function is applied:

            * 0 or 'index': apply function to each column.
            * 1 or 'columns': apply function to each row.

        raw : bool, default False
            Determines if row or column is passed as a Series or ndarray object:

            * ``False`` : passes each row or column as a Series to the
              function.
            * ``True`` : the passed function will receive ndarray objects
              instead.

        result_type : {'expand', 'reduce', 'broadcast', None}, default None
            These only act when ``axis=1`` (columns):

            * 'expand' : list-like results will be turned into columns.
            * 'reduce' : returns a Series if possible rather than expanding
              list-like results. This is the opposite of 'expand'.
            * 'broadcast' : results will be broadcast to the original shape
              of the DataFrame, the original index and columns will be
              retained.

            Snowpark pandas does not yet support the ``result_type`` parameter.

        args : tuple
            Positional arguments to pass to `func` in addition to the
            array/series.

        **kwargs
            Additional keyword arguments to pass as keywords arguments to
            `func`.

        Returns
        -------
        Series or DataFrame
            Result of applying ``func`` along the given axis of the DataFrame.

        See Also
        --------
        :func:`Series.apply <modin.pandas.Series.apply>` : For applying more complex functions on a Series.

        :func:`DataFrame.applymap <modin.pandas.DataFrame.applymap>` : Apply a function elementwise on a whole DataFrame.

        Notes
        -----
        1. When ``func`` has a type annotation for its return value, the result will be cast
        to the corresponding dtype. When no type annotation is provided, data will be converted
        to VARIANT type in Snowflake, and the result will have ``dtype=object``. In this case, the return value must
        be JSON-serializable, which can be a valid input to ``json.dumps`` (e.g., ``dict`` and
        ``list`` objects are JSON-serializable, but ``bytes`` and ``datetime.datetime`` objects
        are not). The return type hint is used only when ``func`` is a series-to-scalar function.

        2. Under the hood, we use Snowflake Vectorized Python UDFs to implement apply() method with
        `axis=1`. You can find type mappings from Snowflake SQL types to pandas dtypes
        `here <https://docs.snowflake.com/en/developer-guide/udf/python/udf-python-batch#type-support>`_.

        3. Snowflake supports two types of NULL values in variant data: `JSON NULL and SQL NULL <https://docs.snowflake.com/en/user-guide/semistructured-considerations#null-values>`_.
        When no type annotation is provided and Variant data is returned, Python ``None`` is translated to
        JSON NULL, and all other pandas missing values (np.nan, pd.NA, pd.NaT) are translated to SQL NULL.

        4. If ``func`` is a series-to-series function that can also be used as a scalar-to-scalar function
        (e.g., ``np.sqrt``, ``lambda x: x+1``), using ``df.applymap()`` to apply the function
        element-wise may give better performance.

        5. When ``func`` can return a series with different indices, e.g.,
        ``lambda x: pd.Series([1, 2], index=["a", "b"] if x.sum() > 2 else ["b", "c"])``,
        the values with the same label will be merged together.

        6. The index values of returned series from ``func`` must be JSON-serializable. For example,
        ``lambda x: pd.Series([1], index=[bytes(1)])`` will raise a SQL execption because python ``bytes``
        objects are not JSON-serializable.

        7. When ``func`` uses any first-party modules or third-party packages inside the function,
        you need to add these dependencies via ``session.add_import()`` and ``session.add_packages()``.

        8. The Snowpark pandas module cannot currently be referenced inside the definition of
        ``func``. If you need to call a general pandas API like ``pd.Timestamp`` inside ``func``,
        please use the original ``pandas`` module (with ``import pandas``) as a workaround.

        9. To create a permanent function, pass the "snowflake_udf_params" dictionary argument to
        ``apply``. See examples below for details.

        Examples
        --------
        >>> df = pd.DataFrame([[2, 0], [3, 7], [4, 9]], columns=['A', 'B'])
        >>> df
           A  B
        0  2  0
        1  3  7
        2  4  9

        Using a reducing function on ``axis=1``:

        >>> df.apply(np.sum, axis=1)
        0     2
        1    10
        2    13
        dtype: int64

        Returning a list-like object will result in a Series:

        >>> df.apply(lambda x: [1, 2], axis=1)
        0    [1, 2]
        1    [1, 2]
        2    [1, 2]
        dtype: object

        To work with 3rd party packages, add them to the current session:

        >>> import scipy.stats
        >>> pd.session.custom_package_usage_config['enabled'] = True
        >>> pd.session.add_packages(['numpy', scipy])
        >>> df.apply(lambda x: np.dot(x * scipy.stats.norm.cdf(0), x * scipy.stats.norm.cdf(0)), axis=1)
        0     1.00
        1    14.50
        2    24.25
        dtype: float64

        To generate a permanent UDTF, pass a dictionary as the `snowflake_udf_params` argument to `apply`.
        The following example generates a permanent UDTF named "permanent_double":

        >>> session.sql("CREATE STAGE sample_upload_stage").collect()  # doctest: +SKIP
        >>> def double(x: int) -> int:  # doctest: +SKIP
        ...     return x * 2
        ...
        >>> df.apply(double, snowflake_udf_params={"name": "permanent_double", "stage_location": "@sample_upload_stage"})  # doctest: +SKIP
           A   B
        0  4   0
        1  6  14
        2  8  18

        You may also pass "replace" and "if_not_exists" in the dictionary to overwrite or re-use existing UDTFs.

        With the "replace" flag:

        >>> df.apply(double, snowflake_udf_params={  # doctest: +SKIP
        ...     "name": "permanent_double",
        ...     "stage_location": "@sample_upload_stage",
        ...     "replace": True,
        ... })

        With the "if_not_exists" flag:

        >>> df.apply(double, snowflake_udf_params={  # doctest: +SKIP
        ...     "name": "permanent_double",
        ...     "stage_location": "@sample_upload_stage",
        ...     "if_not_exists": True,
        ... })

        Note that Snowpark pandas may still attempt to upload a new UDTF even when "if_not_exists"
        is passed; the generated SQL will just contain a `CREATE FUNCTION IF NOT EXISTS` query
        instead. Subsequent calls to `apply` within the same session may skip this query.

        Passing the `immutable` keyword creates an immutable UDTF, which assumes that the
        UDTF will return the same result for the same inputs.

        >>> df.apply(double, snowflake_udf_params={  # doctest: +SKIP
        ...     "name": "permanent_double",
        ...     "stage_location": "@sample_upload_stage",
        ...     "replace": True,
        ...     "immutable": True,
        ... })
        """

    def assign():
        """
        Assign new columns to a ``DataFrame``.

        Returns a new object with all original columns in addition to new ones. Existing
        columns that are re-assigned will be overwritten.

        Parameters
        ----------
        **kwargs: dict of {str: callable or Series}
            The column names are the keywords. If the values are callable, they are computed
            on the DataFrame and assigned to the new columns. The callable must not change input
            DataFrame (though Snowpark pandas doesn't check it). If the values are not callable,
            (e.g. a Series, scalar, or array), they are simply assigned.

        Returns
        -------
        DataFrame
            A new DataFrame with the new columns in addition to all the existing columns.

        Notes
        -----
        - Assigning multiple columns within the same assign is possible. Later items in `**kwargs`
          may refer to newly created or modified columns in `df`; items are computed and assigned into `df` in order.

        - If an array that of the wrong length is passed in to assign, Snowpark pandas will either truncate the array, if it is too long,
          or broadcast the last element of the array until the array is the correct length if it is too short. This differs from native pandas,
          which will error out with a ValueError if the length of the array does not match the length of `df`.
          This is done to preserve Snowpark pandas' lazy evaluation paradigm.

        Examples
        --------
        >>> df = pd.DataFrame({'temp_c': [17.0, 25.0]},

    def groupby():
        """
        Group DataFrame using a mapper or by a Series of columns.

        Args:
            by: mapping, function, label, Snowpark pandas Series or a list of such. Used to determine the groups for the groupby.
                If by is a function, it’s called on each value of the object’s index. If a dict or Snowpark pandas Series is
                passed, the Series or dict VALUES will be used to determine the groups (the Series’ values are first aligned;
                see .align() method). If a list or ndarray of length equal to the selected axis is passed (see the groupby
                user guide), the values are used as-is to determine the groups. A label or list of labels may be passed
                to group by the columns in self. Notice that a tuple is interpreted as a (single) key.

            axis: {0 or ‘index’, 1 or ‘columns’}, default 0
                Split along rows (0) or columns (1). For Series this parameter is unused and defaults to 0.

            level: int, level name, or sequence of such, default None
                If the axis is a MultiIndex (hierarchical), group by a particular level or levels. Do not specify both by and level.

            as_index: bool, default True
                    For aggregated output, return object with group labels as the index. Only relevant for DataFrame input.
                    as_index=False is effectively “SQL-style” grouped output.

            sort: bool, default True
                Sort group keys. Groupby preserves the order of rows within each group. Note that in pandas,
                better performance can be achieved by turning sort off, this is not going to be true with
                SnowparkPandas. When sort=False, the performance will be no better than sort=True.

            group_keys: bool, default True
                    When calling apply and the by argument produces a like-indexed (i.e. a transform) result, add group
                    keys to index to identify pieces. By default group keys are not included when the result’s index
                    (and column) labels match the inputs, and are included otherwise.

            observed: bool, default False
                    This only applies if any of the groupers are Categoricals. If True: only show observed values for
                    categorical groupers. If False: show all values for categorical groupers. This parameter is
                    currently ignored with Snowpark pandas API, since Category type is currently not supported with
                    Snowpark pandas API.

            dropna: bool, default True
                    If True, and if group keys contain NA values, NA values together with row/column will be dropped.
                    If False, NA values will also be treated as the key in groups.

        Returns:
            Snowpark pandas DataFrameGroupBy: Returns a groupby object that contains information about the groups.

        Examples::

            **Hierarchical Indexes**

            We can groupby different levels of a hierarchical index
            using the `level` parameter:

            >>> arrays = [['Falcon', 'Falcon', 'Parrot', 'Parrot'],
            ...           ['Captive', 'Wild', 'Captive', 'Wild']]

            Function to use for transforming the data. If a function, must either work when passed
            a DataFrame or when passed to DataFrame.apply. If func is both list-like and dict-like,

        Args:
            *args tuple, optional

            copy bool, default False
                Whether to copy the data after transposing, even for DataFrames with a single dtype.  The snowpark
                pandas implementation ignores this parameter.

            Note that a copy is always required for mixed dtype DataFrames, or for DataFrames with any extension types.

        Returns:
            DataFrame
                The transposed DataFrame.

        Examples::
            Square DataFrame with homogeneous dtype

            >>> d1 = {'col1': [1, 2], 'col2': [3, 4]}
            >>> df1 = pd.DataFrame(data=d1)

            When the dtype is homogeneous in the original DataFrame, we get a transposed DataFrame with the same dtype:

            kids          0     0

            When the DataFrame has mixed dtypes, we get a transposed DataFrame with the object dtype:

If method is not specified, this is the maximum number of entries along the entire axis where NaNs will be filled. Must be greater than 0 if not None.
        limit_area : {None, ‘inside’, ‘outside’}, default None
            If limit is specified, consecutive NaNs will be filled with this restriction.
            - None: No fill restriction.
            - ‘inside’: Only fill NaNs surrounded by valid values (interpolate).
            - ‘outside’: Only fill NaNs outside valid values (extrapolate).
        downcast : dict, default is None
            A dict of item->dtype of what to downcast if possible, or the string ‘infer’ which will try to downcast to an appropriate equal type (e.g. float64 to int64 if possible).

        Deprecated parameter.

        Returns
        -------

    def boxplot():
        """
        Make a box plot from DataFrame columns.

        Make a box-and-whisker plot from DataFrame columns, optionally grouped by some other columns. A box plot is a method for graphically depicting groups of numerical data through their quartiles. The box extends from the Q1 to Q3 quartile values of the data, with a line at the median (Q2). The whiskers extend from the edges of box to show the range of the data. By default, they extend no more than 1.5 * IQR (IQR = Q3 - Q1) from the edges of the box, ending at the farthest data point within that interval. Outliers are plotted as separate dots.

        For further details see Wikipedia’s entry for [boxplot](https://en.wikipedia.org/wiki/Box_plot).

        Parameters
        ----------
        column : str or list of str, optional
            Column name or list of names, or vector. Can be any valid input to pandas.DataFrame.groupby().

        by : str or array-like, optional
            Column in the DataFrame to pandas.DataFrame.groupby(). One box-plot will be done per value of columns in by.

        ax : object of class matplotlib.axes.Axes, optional
            The matplotlib axes to be used by boxplot.

        fontsize : float or str
            Tick label font size in points or as a string (e.g., large).

        rot : float, default 0
            The rotation angle of labels (in degrees) with respect to the screen coordinate system.

        grid : bool, default True
            Setting this to True will show the grid.

        fig : sizeA tuple (width, height) in inches
            The size of the figure to create in matplotlib.

        layout : tuple (rows, columns), optional
            For example, (3, 5) will display the subplots using 3 rows and 5 columns, starting from the top-left.

        return_type : {‘axes’, ‘dict’, ‘both’} or None, default ‘axes’
            The kind of object to return. The default is axes.

            - ‘axes’ returns the matplotlib axes the boxplot is drawn on.

            - ‘dict’ returns a dictionary whose values are the matplotlib Lines of the boxplot.

            - ‘both’ returns a namedtuple with the axes and dict.

            - when grouping with by, a Series mapping columns to return_type is returned.

            If return_type is None, a NumPy array of axes with the same shape as layout is returned.

        backend : str, default None
            Backend to use instead of the backend specified in the option plotting.backend. For instance, ‘matplotlib’. Alternatively, to specify the plotting.backend for the whole session, set pd.options.plotting.backend.

        **kwargs
            All other plotting keyword arguments to be passed to matplotlib.pyplot.boxplot().

        Returns
        -------
        result
            See Notes.

        See also
        --------
        Series.plot.hist
            Make a histogram.

        matplotlib.pyplot.boxplot
            Matplotlib equivalent plot.

        Notes
        -----
        The return type depends on the return_type parameter:

        - ‘axes’ : object of class matplotlib.axes.Axes

        - ‘dict’ : dict of matplotlib.lines.Line2D objects

        - ‘both’ : a namedtuple with structure (ax, lines)

        For data grouped with by, return a Series of the above or a numpy array:

        - Series

        - array (for return_type = None)

        Use return_type='dict' when you want to tweak the appearance of the lines after plotting. In this case a dict containing the Lines making up the boxes, caps, fliers, medians, and whiskers is returned.

        Examples
        --------
        Boxplots can be created for every column in the dataframe by df.boxplot() or indicating the columns to be used:

        >>> np.random.seed(1234)
        >>> df = pd.DataFrame(np.random.randn(10, 4),
        ...                   columns=['Col1', 'Col2', 'Col3', 'Col4'])
        >>> boxplot = df.boxplot(column=['Col1', 'Col2', 'Col3'])

        Boxplots of variables distributions grouped by the values of a third variable can be created using the option by. For instance:

        >>> df = pd.DataFrame(np.random.randn(10, 2),
        ...                   columns=['Col1', 'Col2'])
        >>> df['X'] = pd.Series(['A', 'A', 'A', 'A', 'A',
        ...                      'B', 'B', 'B', 'B', 'B'])
        >>> boxplot = df.boxplot(by='X')

        A list of strings (i.e. ['X', 'Y']) can be passed to boxplot in order to group the data by combination of the variables in the x-axis:

        >>> df = pd.DataFrame(np.random.randn(10, 3),
        ...                   columns=['Col1', 'Col2', 'Col3'])
        >>> df['X'] = pd.Series(['A', 'A', 'A', 'A', 'A',
        ...                      'B', 'B', 'B', 'B', 'B'])
        >>> df['Y'] = pd.Series(['A', 'B', 'A', 'B', 'A',
        ...                      'B', 'A', 'B', 'A', 'B'])
        >>> boxplot = df.boxplot(column=['Col1', 'Col2'], by=['X', 'Y'])

        The layout of boxplot can be adjusted giving a tuple to layout:

        >>> boxplot = df.boxplot(column=['Col1', 'Col2'], by='X',
        ...                      layout=(2, 1))

        Additional formatting can be done to the boxplot, like suppressing the grid (grid=False), rotating the labels in the x-axis (i.e. rot=45) or changing the fontsize (i.e. fontsize=15):

        >>> boxplot = df.boxplot(grid=False, rot=45, fontsize=15)  # doctest: +SKIP

        The parameter return_type can be used to select the type of element returned by boxplot. When return_type='axes' is selected, the matplotlib axes on which the boxplot is drawn are returned:

        >>> boxplot = df.boxplot(column=['Col1', 'Col2'], return_type='axes')
        >>> type(boxplot)
        <class 'matplotlib.axes._axes.Axes'>

        When grouping with by, a Series mapping columns to return_type is returned:

        >>> boxplot = df.boxplot(column=['Col1', 'Col2'], by='X',
        ...                      return_type='axes')
        >>> type(boxplot)
        <class 'pandas.core.series.Series'>

        If return_type is None, a NumPy array of axes with the same shape as layout is returned:

        >>> boxplot = df.boxplot(column=['Col1', 'Col2'], by='X',
        ...                      return_type=None)
        >>> type(boxplot)
        <class 'numpy.ndarray'>

        Test whether two dataframes contain the same elements.

        This function allows two DataFrames to be compared against
        each other to see if they have the same shape and elements. NaNs in
        the same location are considered equal.

        The row/column index do not need to have the same type, as long
        as the values are considered equal. Corresponding columns and
        index must be of the same dtype. Note: int variants (int8, int16 etc) are
        considered equal dtype i.e int8 == int16. Similarly, float variants (float32,
        float64 etc) are considered equal dtype.

        Parameters
        ----------
        other : DataFrame
            The other DataFrame to be compared with the first.

        Returns

            element in each DataFrame is equal, False otherwise.
        testing.assert_series_equal : Raises an AssertionError if left and

        Parameters
        ----------
        data : structured ndarray, sequence of tuples or dicts, or DataFrame
            Structured input data.

            Deprecated: Passing a DataFrame is deprecated.

        index : str, list of fields, array-like
            Field of array to use as the index, alternately a specific set of input labels to use.
        exclude : sequence, default None
            Columns or fields to exclude.
        columns : sequence, default None
            Column names to use. If the passed data do not have names associated with them, this argument provides names for the columns. Otherwise this argument indicates the order of the columns in the result (any names not found in the data will become all-NA columns).
        coerce_float : bool, default False
            Attempt to convert values of non-string, non-numeric objects (like decimal.Decimal) to floating point, useful for SQL result sets.
        nrows : int, default None
            Number of rows to read if data is an iterator.

        Returns
        -------
        DataFrame

        See also
        --------
        DataFrame.from_dict
            DataFrame from dict of array-like or dicts.
        DataFrame
            DataFrame object creation using constructor.

        Examples
        --------
        Data can be provided as a structured ndarray:

        Print a concise summary of the ``DataFrame``. Snowflake
        DataFrames mirror the output of pandas df.info but with some
        specific limitations ( zeroed memory usage, no index information ).

        Parameters
        ----------
        verbose : bool, optional
            Whether to print the full summary. By default, the setting in
            ``pandas.options.display.max_info_columns`` is followed.
        buf : writable buffer, defaults to sys.stdout
            Where to send the output. By default, the output is printed to
            sys.stdout. Pass a writable buffer if you need to further process
            the output.
        max_cols : int, optional
            When to switch from the verbose to the truncated output. If the
            DataFrame has more than `max_cols` columns, the truncated output
            is used. By default, the setting in
            ``pandas.options.display.max_info_columns`` is used.
        memory_usage : bool, str, optional
            Displays 0 for memory usage, since the memory usage of a snowflake
            dataframe is remote and partially indeterminant.
        show_counts : bool, optional
            Whether to show the non-null counts. By default, this is shown
            only if the DataFrame is smaller than
            ``pandas.options.display.max_info_rows`` and
            ``pandas.options.display.max_info_columns``. A value of True always
            shows the counts, and False never shows the counts.

        Iterate over ``DataFrame`` rows as (index, ``Series``) pairs.

        Yields
        ------
        index : label or tuple of label
            The index of the row. A tuple for a `MultiIndex`.

        DataFrame.items : Iterate over (column name, Series) pairs.

        Notes
        -----
        1. Iterating over rows is an antipattern in Snowpark pandas and pandas. Use df.apply() or other aggregation
           methods when possible instead of iterating over a DataFrame. Iterators and for loops do not scale well.
        2. Because ``iterrows`` returns a Series for each row, it does **not** preserve dtypes across the rows (dtypes
           are preserved across columns for DataFrames).
        3. You should **never modify** something you are iterating over. This will not work. The iterator returns a copy
           of the data and writing to it will have no effect.

        Examples
        --------

        Parameters
        ----------
        other : DataFrame, Series, or a list containing any combination of them
            Index should be similar to one of the columns in this one. If a
            Series is passed, its name attribute must be set, and that will be
            used as the column name in the resulting joined DataFrame.
        on : str, list of str, or array-like, optional
            Column or index level name(s) in the caller to join on the index
            in `other`, otherwise joins index-on-index. If multiple
            values given, the `other` DataFrame must have a MultiIndex. Can
            pass an array as the join key if it is not already contained in
            the calling DataFrame. Like an Excel VLOOKUP operation.
        how : {'left', 'right', 'outer', 'inner'}, default 'left'
            How to handle the operation of the two objects.

            * left: use calling frame's index (or column if on is specified)
            * right: use `other`'s index.
            * outer: form union of calling frame's index (or column if on is
              specified) with `other`'s index, and sort it.
              lexicographically.
            * inner: form intersection of calling frame's index (or column if
              on is specified) with `other`'s index, preserving the order
              of the calling's one.
            * cross: creates the cartesian product from both frames, preserves the order
              of the left keys.
        lsuffix : str, default ''
            Suffix to use from left frame's overlapping columns.
        rsuffix : str, default ''
            Suffix to use from right frame's overlapping columns.
        sort : bool, default False
            Order result DataFrame lexicographically by the join key. If False,
            the order of the join key depends on the join type (how keyword).
        validate : str, optional
            If specified, checks if join is of specified type.
            * "one_to_one" or "1:1": check if join keys are unique in both left
            and right datasets.
            * "one_to_many" or "1:m": check if join keys are unique in left dataset.
            * "many_to_one" or "m:1": check if join keys are unique in right dataset.
            * "many_to_many" or "m:m": allowed, but does not result in checks.

        Returns
        -------
        DataFrame
            A dataframe containing columns from both the caller and `other`.

        Notes
        -----
        Parameters `on`, `lsuffix`, and `rsuffix` are not supported when
        passing a list of `DataFrame` objects.

        Snowpark pandas API doesn't currently support distributed computation of join with
        'validate' argument.

            >>> df = pd.DataFrame({'key': ['K0', 'K1', 'K2', 'K3', 'K4', 'K5'],
            ...                    'A': ['A0', 'A1', 'A2', 'A3', 'A4', 'A5']})

            >>> df
              key   A
            0  K0  A0
            1  K1  A1
            2  K2  A2

            >>> other
              key   B
            0  K0  B0
            1  K1  B1
            2  K2  B2

            Join DataFrames using their indexes.

            >>> df.join(other, lsuffix='_caller', rsuffix='_other')
              key_caller   A key_other     B
            0         K0  A0        K0    B0
            1         K1  A1        K1    B1
            2         K2  A2        K2    B2
            3         K3  A3      None  None
            4         K4  A4      None  None
            5         K5  A5      None  None

            If we want to join using the key columns, we need to set key to be
            the index in both `df` and `other`. The joined DataFrame will have
            key as its index.

            >>> df.set_index('key').join(other.set_index('key'))  # doctest: +NORMALIZE_WHITESPACE
                  A     B
            key
            K0   A0    B0
            K1   A1    B1
            K2   A2    B2
            K3   A3  None
            K4   A4  None
            K5   A5  None

            Another option to join using the key columns is to use the `on`
            parameter. DataFrame.join always uses `other`'s index but we can use
            any column in `df`. This method preserves the original DataFrame's
            index in the result.

            >>> df.join(other.set_index('key'), on='key')
              key   A     B
            0  K0  A0    B0
            1  K1  A1    B1
            2  K2  A2    B2
            3  K3  A3  None
            4  K4  A4  None
            5  K5  A5  None

            Using non-unique key values shows how they are matched.

            >>> df = pd.DataFrame({'key': ['K0', 'K1', 'K1', 'K3', 'K0', 'K1'],
            ...                    'A': ['A0', 'A1', 'A2', 'A3', 'A4', 'A5']})

            >>> df
              key   A
            0  K0  A0
            1  K1  A1
            2  K1  A2
            3  K3  A3

        In the following example, we will use ``nlargest`` to select the three
        rows having the largest values in column "population".

        >>> df.nlargest(3, 'population')
                population      GDP alpha-2
        France    65000000  2583560      FR

        Malta       434000    12011      MT

        When using ``keep='last'``, ties are resolved in reverse order:

        >>> df.nlargest(3, 'population', keep='last')
                population      GDP alpha-2
        France    65000000  2583560      FR
        Italy     59000000  1937894      IT
        Brunei      434000    12128      BN

        When using ``keep='all'``, the number of element kept can go beyond ``n``
        if there are duplicate values for the smallest element, all the
        ties are kept:

        >>> df.nlargest(3, 'population', keep='all')  # doctest: +SKIP
                  population      GDP alpha-2
        France      65000000  2583560      FR
        Italy       59000000  1937894      IT
        Malta         434000    12011      MT
        Maldives      434000     4520      MV
        Brunei        434000    12128      BN

        However, ``nlargest`` does not keep ``n`` distinct largest elements:

        >>> df.nlargest(5, 'population', keep='all')  # doctest: +SKIP
                  population      GDP alpha-2
        France      65000000  2583560      FR
        Italy       59000000  1937894      IT
        Malta         434000    12011      MT
        Maldives      434000     4520      MV
        Brunei        434000    12128      BN

        To order by the largest values in column "population" and then "GDP",
        we can specify multiple columns like in the next example.

        >>> df.nlargest(3, ['population', 'GDP'])
                population      GDP alpha-2
        France    65000000  2583560      FR

        In the following example, we will use ``nsmallest`` to select the
        three rows having the smallest values in column "population".

        >>> df.nsmallest(3, 'population')
                  population    GDP alpha-2

        When using ``keep='last'``, ties are resolved in reverse order:

        >>> df.nsmallest(3, 'population', keep='last')
                  population  GDP alpha-2
        Anguilla       11300  311      AI
        Tuvalu         11300   38      TV
        Nauru         337000  182      NR

        When using ``keep='all'``, the number of element kept can go beyond ``n``.
        if there are duplicate values for the largest element, all the
        ties are kept.

        >>> df.nsmallest(3, 'population', keep='all')  # doctest: +SKIP
                  population    GDP alpha-2
        Tuvalu         11300     38      TV

        Nauru         337000    182      NR

        However, ``nsmallest`` does not keep ``n`` distinct
        smallest elements:

        >>> df.nsmallest(4, 'population', keep='all')  # doctest: +SKIP
                  population    GDP alpha-2
        Tuvalu         11300     38      TV

        Nauru         337000    182      NR

        To order by the smallest values in column "population" and then "GDP", we can
        specify multiple columns like in the next example.

    def unstack():
        """
        Pivot a level of the (necessarily hierarchical) index labels.

        Returns a DataFrame having a new level of column labels whose
        inner-most level consists of the pivoted index labels.

        If the index is not a MultiIndex, the output will be a Series
        (the analogue of stack when the columns are not a MultiIndex).

        Parameters
        ----------
        level : int, str, list, default -1
            Level(s) of index to unstack, can pass level name.

        fillna : int, str, dict, optional
            Replace NaN with this value if the unstack produces missing values.

        sort : bool, default True
            Sort the level(s) in the resulting MultiIndex columns.

        Returns
        -------
        Series or DataFrame

        Notes
        -----
        Supports only integer ``level`` and ``sort = True``. Internally, calls ``pivot_table``
        or ``melt`` to perform `unstack` operation.

        --------
        DataFrame.pivot : Pivot without aggregation that can handle
            non-numeric data.

        Reshape data (produce a "pivot" table) based on column values. Uses unique values from
        specified index / columns to form axes of the resulting DataFrame. This function does not
        support data aggregation, multiple values will result in a MultiIndex in the columns.

        Parameters
        ----------
        columns : str or object or a list of str
            Column to use to make new frame’s columns.
        index : str or object or a list of str, optional

    def pivot_table():
        """
        Create a spreadsheet-style pivot table as a ``DataFrame``.

        The levels in the pivot table will be stored in MultiIndex objects
        (hierarchical indexes) on the index and columns of the result DataFrame.

        Parameters
        ----------
        values : list-like or scalar, optional
            Column or columns to aggregate.
        index : column, Grouper, array, or list of the previous
            Keys to group by on the pivot table index. If a list is passed,
            it can contain any of the other types (except list). If an array is
            passed, it must be the same length as the data and will be used in
            the same manner as column values.
        columns : column, Grouper, array, or list of the previous
            Keys to group by on the pivot table column. If a list is passed,
            it can contain any of the other types (except list). If an array is
            passed, it must be the same length as the data and will be used in
            the same manner as column values.
        aggfunc : function, list of functions, dict in string, default "mean".
            If a list of functions is passed, the resulting pivot table will have
            hierarchical columns whose top level are the function names
            (inferred from the function objects themselves).
            If a dict is passed, the key is column to aggregate and the value is
            function or list of functions. If ``margin=True``, aggfunc will be
            used to calculate the partial aggregates.
        fill_value : scalar, default None
            Value to replace missing values with (in the resulting pivot table,
            after aggregation).
        margins : bool, default False
            If ``margins=True``, special ``All`` columns and rows
            will be added with partial group aggregates across the categories
            on the rows and columns.
        dropna : bool, default True
            Do not include columns whose entries are all NaN. If True,
            rows with a NaN value in any column will be omitted before
            computing margins.
        margins_name : str, default 'All'
            Name of the row / column that will contain the totals
            when margins is True.
        observed : bool, default False
            This only applies if any of the groupers are Categoricals.
            If True: only show observed values for categorical groupers.
            If False: show all values for categorical groupers.

        sort : bool, default True
            Specifies if the result should be sorted.

        Returns
        -------
        DataFrame
            An Excel style pivot table.

        Notes
        -----
        - Raise NotImplementedError if

            * observed or sort is given;
            * or index, columns, or values is not str, a list of str, or None;
            * or DataFrame contains MultiIndex;
            * or any aggfunc is not "count", "mean", "min", "max", or "sum"
            * index is None, and aggfunc is a dictionary containing lists.

        - Computing margins with no index has limited support:
            * when aggfunc is "count" or "mean" the result has discrepancies with pandas -
              Snowpark pandas computes the aggfunc over the data grouped by the first pivot
              column, while pandas computes the aggfunc over the result of the aggfunc from
              the initial pivot.
            * aggfunc as a dictionary is not supported.

        Return values at the given quantile over requested axis.

        Parameters
        ----------
        q: float or array-like of float, default 0.5
            Value between 0 <= q <= 1, the quantile(s) to compute.
        axis: {0 or 'index', 1 or 'columns'}, default 0
            Axis across which to compute quantiles.
        numeric_only: bool, default False
            Include only data where `is_numeric_dtype` is true.
            When True, bool columns are included, but attempting to compute quantiles across
            bool values is an ill-defined error in both pandas and Snowpark pandas.
        interpolation: {"linear", "lower", "higher", "midpoint", "nearest"}, default "linear"
            Specifies the interpolation method to use if a quantile lies between two data points
            *i* and *j*:

            * linear: *i* + (*j* - *i*) * *fraction*, where *fraction* is the fractional part of the

            Snowpark pandas currently only supports "linear" and "nearest".

            Whether to compute quantiles per-column ("single") or over all columns ("table").
            When "table", the only allowed interpolation methods are "nearest", "lower", and "higher".

        Returns
        -------
        Series or DataFrame
            If ``q`` is an array, a DataFrame will be returned where the index is ``q``, the columns
            are the columns of ``self``, and the values are the quantiles.
            If ``q`` is a float, a Series will be returned where the index is the columns of
            ``self`` and the values are the quantiles.

        Examples
        --------
        >>> df = pd.DataFrame(np.array([[1, 1], [2, 10], [3, 100], [4, 100]]), columns=['a', 'b'])

        With a scalar q:

        """

    def query():
        """
        Query the columns of a DataFrame with a boolean expression.

        Parameters
        ----------
        expr : str
            The query string to evaluate.

            You can refer to variables
            in the environment by prefixing them with an '@' character like
            ``@a + b``.

            You can refer to column names that are not valid Python variable names
            by surrounding them in backticks. Thus, column names containing spaces
            or punctuations (besides underscores) or starting with digits must be
            surrounded by backticks. (For example, a column named "Area (cm^2)" would
            be referenced as ```Area (cm^2)```). Column names which are Python keywords
            (like "list", "for", "import", etc) cannot be used.

            For example, if one of your columns is called ``a a`` and you want
            to sum it with ``b``, your query should be ```a a` + b``.

        inplace : bool
            Whether to modify the DataFrame rather than creating a new one.

        **kwargs
            See the documentation for :func:`eval` for complete details
            on the keyword arguments accepted by :meth:`DataFrame.query`.

        Returns
        -------
        DataFrame or None
            DataFrame resulting from the provided query expression or
            None if ``inplace=True``.

        See Also
        --------
        eval : Evaluate a string describing operations on
            DataFrame columns.
        DataFrame.eval : Evaluate a string describing operations on
            DataFrame columns.

        Notes
        -----
        The result of the evaluation of this expression is first passed to
        :attr:`DataFrame.loc` and if that fails because of a
        multidimensional key (e.g., a DataFrame) then the result will be passed
        to :meth:`DataFrame.__getitem__`.

        This method uses the top-level :func:`eval` function to
        evaluate the passed query.

        The :meth:`query` method uses a slightly
        modified Python syntax by default. For example, the ``&`` and ``|``
        (bitwise) operators have the precedence of their boolean cousins,
        :keyword:`and` and :keyword:`or`. This *is* syntactically valid Python,
        however the semantics are different.

        You can change the semantics of the expression by passing the keyword
        argument ``parser='python'``. This enforces the same semantics as
        evaluation in Python space.

        The :attr:`DataFrame.index` and
        :attr:`DataFrame.columns` attributes of the
        :class:`DataFrame` instance are placed in the query namespace
        by default, which allows you to treat both the index and columns of the
        frame as a column in the frame.
        The identifier ``index`` is used for the frame index; you can also
        use the name of the index to identify it in a query. Please note that
        Python keywords may not be used as identifiers.

        *Backtick quoted variables*

        Backtick quoted variables are parsed as literal Python code and
        are converted internally to a Python valid identifier.
        This can lead to the following problems.

        During parsing a number of disallowed characters inside the backtick
        quoted string are replaced by strings that are allowed as a Python identifier.
        These characters include all operators in Python, the space character, the
        question mark, the exclamation mark, the dollar sign, and the euro sign.
        For other characters that fall outside the ASCII range (U+0001..U+007F)
        and those that are not further specified in PEP 3131,
        the query parser will raise an error.
        This excludes whitespace different than the space character,
        but also the hashtag (as it is used for comments) and the backtick
        itself (backtick can also not be escaped).

        In a special case, quotes that make a pair around a backtick can
        confuse the parser.
        For example, ```it's` > `that's``` will raise an error,
        as it forms a quoted string (``'s > `that'``) with a backtick inside.

        See also the Python documentation about lexical analysis
        (https://docs.python.org/3/reference/lexical_analysis.html).

        Examples
        --------
        >>> df = pd.DataFrame({'A': range(1, 6),
        ...                    'B': range(10, 0, -2),
        ...                    'C C': range(10, 5, -1)})
        >>> df
           A   B  C C
        0  1  10   10
        1  2   8    9
        2  3   6    8
        3  4   4    7

        >>> df.query('A > B')
           A  B  C C
        4  5  2    6

        The previous expression is equivalent to

        >>> df[df.A > df.B]
           A  B  C C
        4  5  2    6

        For columns with spaces in their name, you can use backtick quoting.

        >>> df.query('B == `C C`')
           A   B  C C
        0  1  10   10

        The previous expression is equivalent to

        >>> df[df.B == df['C C']]
           A   B  C C
        0  1  10   10

    def rename():
        """
        Rename columns or index labels.

        Function / dict values must be unique (1-to-1). Labels not contained in
        a dict / Series will be left as-is. Extra labels listed don't throw an
        error.

        Parameters
        ----------
        mapper : dict-like or function
            Dict-like or function transformations to apply to
            that axis' values. Use either ``mapper`` and ``axis`` to
            specify the axis to target with ``mapper``, or ``index`` and
            ``columns``.
        index : dict-like or function
            Alternative to specifying axis (``mapper, axis=0``
            is equivalent to ``index=mapper``).
        columns : dict-like or function
            Alternative to specifying axis (``mapper, axis=1``
            is equivalent to ``columns=mapper``).
        axis : {0 or 'index', 1 or 'columns'}, default 0
            Axis to target with ``mapper``. Can be either the axis name
            ('index', 'columns') or number (0, 1). The default is 'index'.
        copy : bool, default True
            Also copy underlying data. copy has been ignored with Snowflake execution engine.
        inplace : bool, default False
            Whether to modify the DataFrame rather than creating a new one.
            If True then value of copy is ignored.
        level : int or level name, default None
            In case of a MultiIndex, only rename labels in the specified
            level.
        errors : {'ignore', 'raise'}, default 'ignore'
            If 'raise', raise a `KeyError` when a dict-like `mapper`, `index`,
            or `columns` contains labels that are not present in the Index
            being transformed.
            If 'ignore', existing keys will be renamed and extra keys will be
            ignored.

        Returns
        -------
        DataFrame or None
            DataFrame with the renamed axis labels or None if ``inplace=True``.

        Raises
        ------
        KeyError
            If any of the labels is not found in the selected axis and
            "errors='raise'".

        See Also
        --------
        DataFrame.rename_axis : Set the name of the axis.

        Examples
        --------
        ``DataFrame.rename`` supports two calling conventions

        * ``(index=index_mapper, columns=columns_mapper, ...)``
        * ``(mapper, axis={'index', 'columns'}, ...)``

        We *highly* recommend using keyword arguments to clarify your
        intent.

        Rename columns using a mapping:

        >>> df = pd.DataFrame({"A": [1, 2, 3], "B": [4, 5, 6]})
        >>> df.rename(columns={"A": "a", "B": "c"})
           a  c
        0  1  4
        1  2  5
        2  3  6

        Rename index using a mapping:

        >>> df.rename(index={0: "x", 1: "y", 2: "z"})
           A  B
        x  1  4
        y  2  5
        z  3  6

        Cast index labels to a different type:

        >>> df.index
        Index([0, 1, 2], dtype='int64')

        >>> df.rename(columns={"A": "a", "B": "b", "C": "c"}, errors="raise")
        Traceback (most recent call last):
          ...
        KeyError: "['C'] not found in axis"

            * pad / ffill: Propagate last valid observation forward to next valid.
            * backfill / bfill: Use next valid observation to fill gap.
            * nearest: Use nearest valid observations to fill gap. Unsupported by Snowpark pandas.

        copy : bool, default True
            Return a new object, even if the passed indexes are the same.

        level : int or name
            Broadcast across a level, matching Index values on the passed MultiIndex level.

        fill_value : scalar, default np.nan
            Value to use for missing values. Defaults to NaN, but can be any “compatible” value.

        limit : int, default None
            Maximum number of consecutive elements to forward or backward fill.

        tolerance : optional
            Maximum distance between original and new labels for inexact matches.
            The values of the index at the matching locations most satisfy the
            equation abs(index[indexer] - target) <= tolerance. Unsupported by
            Snowpark pandas.

        Returns
        -------
        DataFrame
            DataFrame with changed index.

        Notes
        -----
        For axis 0, Snowpark pandas' behaviour diverges from vanilla pandas in order
        to maintain Snowpark's lazy execution paradigm. The behaviour changes are as follows:

            * Snowpark pandas does not error if the existing index is not monotonically increasing
              or decreasing when `method` is specified for filling. It instead assumes that
              the index is monotonically increasing, performs the reindex, and fills the values
              as though the index is sorted (which involves sorting internally).
            * Snowpark pandas does not error out if there are duplicates - they are included in the
              output.
            * Snowpark pandas does not error if a `limit` value is passed and the new index is not
              monotonically increasing or decreasing - instead, it reindexes, sorts the new index,
              fills using limit, and then reorders the data to be in the correct order (the order
              of the target labels passed in to the method).

        For axis 1, Snowpark pandas' error checking remains the same as vanilla pandas.

        MultiIndex is currently unsupported.

        ``method="nearest"`` is currently unsupported.

        Examples
        --------
        Create a dataframe with some fictional data.

        >>> index = ['Firefox', 'Chrome', 'Safari', 'IE10', 'Konqueror']
        >>> df = pd.DataFrame({'http_status': [200, 200, 404, 404, 301],
        ...             'response_time': [0.04, 0.02, 0.07, 0.08, 1.0]},
        ...             index=index)
        >>> df
                   http_status  response_time
        Firefox            200           0.04
        Chrome             200           0.02
        Safari             404           0.07
        IE10               404           0.08
        Konqueror          301           1.00

        Create a new index and reindex the dataframe. By default, values in the new index
        that do not have corresponding records in the dataframe are assigned NaN.

        >>> new_index = ['Safari', 'Iceweasel', 'Comodo Dragon', 'IE10',
        ...              'Chrome']
        >>> df.reindex(new_index)
                       http_status  response_time
        Safari               404.0           0.07
        Iceweasel              NaN            NaN
        Comodo Dragon          NaN            NaN

        Chrome               200.0           0.02

        We can fill in the missing values by passing a value to the keyword fill_value.

        We can also reindex the columns.

        >>> df.reindex(columns=['http_status', 'user_agent']) # doctest: +NORMALIZE_WHITESPACE
                   http_status   user_agent

        Konqueror          301         None

        Or we can use “axis-style” keyword arguments

        >>> df.reindex(['http_status', 'user_agent'], axis="columns")  # doctest: +NORMALIZE_WHITESPACE
                   http_status   user_agent
        Firefox            200         None
        Chrome             200         None
        Safari             404         None
        IE10               404         None
        Konqueror          301         None

        To further illustrate the filling functionality in reindex, we will create a dataframe
        with a monotonically increasing index (for example, a sequence of dates).

        >>> date_index = pd.date_range('1/1/2010', periods=6, freq='D')
        >>> df2 = pd.DataFrame({"prices": [100, 101, np.nan, 100, 89, 88]},
        ...                    index=date_index)
        >>> df2
                    prices
        2010-01-01   100.0
        2010-01-02   101.0
        2010-01-03     NaN
        2010-01-04   100.0
        2010-01-05    89.0
        2010-01-06    88.0

        Suppose we decide to expand the dataframe to cover a wider date range.

        >>> date_index2 = pd.date_range('12/29/2009', periods=10, freq='D')
        >>> df2.reindex(date_index2)
                    prices
        2009-12-29     NaN
        2009-12-30     NaN
        2009-12-31     NaN
        2010-01-01   100.0
        2010-01-02   101.0
        2010-01-03     NaN
        2010-01-04   100.0
        2010-01-05    89.0
        2010-01-06    88.0
        2010-01-07     NaN

        The index entries that did not have a value in the original data frame (for example,
        ``2009-12-29``) are by default filled with NaN. If desired, we can fill in the missing
        values using one of several options.

        For example, to back-propagate the last valid value to fill the NaN values, pass bfill as
        an argument to the method keyword.

        >>> df2.reindex(date_index2, method='bfill')
                    prices
        2009-12-29   100.0
        2009-12-30   100.0
        2009-12-31   100.0
        2010-01-01   100.0
        2010-01-02   101.0
        2010-01-03     NaN
        2010-01-04   100.0
        2010-01-05    89.0
        2010-01-06    88.0
        2010-01-07     NaN

        Please note that the NaN value present in the original dataframe (at index value 2010-01-03) will
        not be filled by any of the value propagation schemes. This is because filling while reindexing
        does not look at dataframe values, but only compares the original and desired indexes. If you do
        want to fill in the NaN values present in the original dataframe, use the fillna() method.

        An example illustrating Snowpark pandas' behavior when dealing with non-monotonic indices.
        >>> unordered_dataframe = pd.DataFrame([[5]*3, [8]*3, [6]*3], columns=list("ABC"), index=[5, 8, 6])
        >>> unordered_dataframe
           A  B  C
        5  5  5  5
        8  8  8  8
        6  6  6  6
        >>> unordered_dataframe.reindex([6, 8, 7], method="ffill")
           A  B  C
        6  6  6  6
        8  8  8  8
        7  6  6  6

        In the example above, index value ``7`` is forward filled from index value ``6``, since that
        is the previous index value when the data is sorted.

    def reindex_like():
        """
        Return an object with matching indices as `other` object.
        """

    def replace():
        """
        Replace values given in `to_replace` with `value`.

        Values of the DataFrame are replaced with other values dynamically.
        This differs from updating with ``.loc`` or ``.iloc``, which require
        you to specify a location to update with some value.

        Parameters
        ----------
        to_replace : str, regex, list, dict, Series, int, float, or None
            How to find the values that will be replaced.

            * numeric, str or regex:

                - numeric: numeric values equal to `to_replace` will be
                  replaced with `value`
                - str: string exactly matching `to_replace` will be replaced
                  with `value`
                - regex: regexs matching `to_replace` will be replaced with
                  `value`

            * list of str, regex, or numeric:

                - First, if `to_replace` and `value` are both lists, they
                  **must** be the same length.
                - Second, if ``regex=True`` then all the strings in **both**
                  lists will be interpreted as regexs otherwise they will match
                  directly. This doesn't matter much for `value` since there
                  are only a few possible substitution regexes you can use.
                - str, regex and numeric rules apply as above.

            * dict:

                - Dicts can be used to specify different replacement values
                  for different existing values. For example,
                  ``{{'a': 'b', 'y': 'z'}}`` replaces the value 'a' with 'b' and
                  'y' with 'z'. To use a dict in this way, the optional `value`
                  parameter should not be given.
                - For a DataFrame a dict can specify that different values
                  should be replaced in different columns. For example,
                  ``{{'a': 1, 'b': 'z'}}`` looks for the value 1 in column 'a'
                  and the value 'z' in column 'b' and replaces these values
                  with whatever is specified in `value`. The `value` parameter
                  should not be ``None`` in this case. You can treat this as a
                  special case of passing two lists except that you are
                  specifying the column to search in.
                - For a DataFrame nested dictionaries, e.g.,
                  ``{{'a': {{'b': np.nan}}}}``, are read as follows: look in column
                  'a' for the value 'b' and replace it with NaN. The optional `value`
                  parameter should not be specified to use a nested dict in this
                  way. You can nest regular expressions as well. Note that
                  column names (the top-level dictionary keys in a nested
                  dictionary) **cannot** be regular expressions.

            * None:

                - This means that the `regex` argument must be a string,
                  compiled regular expression, or list, dict, ndarray or
                  Series of such elements. If `value` is also ``None`` then
                  this **must** be a nested dictionary or Series.

            See the examples section for examples of each of these.
        value : scalar, dict, list, str, regex, default None
            Value to replace any values matching `to_replace` with.
            For a DataFrame a dict of values can be used to specify which
            value to use for each column (columns not in the dict will not be
            filled). Regular expressions, strings and lists or dicts of such
            objects are also allowed.
        inplace : bool, default False
            Whether to modify the DataFrame rather than creating a new one.
        limit : int, default None
            Maximum size gap to forward or backward fill.
            This parameter is not supported.
        regex : bool or same types as `to_replace`, default False
            Whether to interpret `to_replace` and/or `value` as regular
            expressions. Alternatively, this could be a regular expression or a
            list, dict, or array of regular expressions in which case
            `to_replace` must be ``None``.
        method : {{'pad', 'ffill', 'bfill'}}
            The method to use when for replacement, when `to_replace` is a
            scalar, list or tuple and `value` is ``None``.
            This parameter is not supported.

        Returns
        -------
        DataFrame
            DataFrame Object after replacement if inplace=False, None otherwise.

        Raises
        ------
        AssertionError
            * If `regex` is not a ``bool`` and `to_replace` is not ``None``.

        TypeError
            * If `to_replace` is not a scalar, array-like, ``dict``, or ``None``
            * If `to_replace` is a ``dict`` and `value` is not a ``list``,
              ``dict``, ``ndarray``, or ``Series``
            * If `to_replace` is ``None`` and `regex` is not compilable
              into a regular expression or is a list, dict, ndarray, or
              Series.
            * When replacing multiple ``bool`` or ``datetime64`` objects and
              the arguments to `to_replace` does not match the type of the
              value being replaced

        ValueError
            * If a ``list`` or an ``ndarray`` is passed to `to_replace` and
              `value` but they are not the same length.

        NotImplementedError
            * If ``method`` or ``limit`` is provided.

        Notes
        -----
        * Regex substitution is performed under the hood using snowflake backend.
          which supports POSIX ERE syntax for regular expressions. Please check usage
          notes for details.
          https://docs.snowflake.com/en/sql-reference/functions-regexp#general-usage-notes
        * Regular expressions only replace string values. If a regular expression is
          created to match floating point numbers, it will only match string data not
          numeric data.
        * This method has *a lot* of options. You are encouraged to experiment
          and play with this method to gain intuition about how it works.

        0   new  abc
        1   new  new
        2  bait  xyz

        When ``regex=True``, ``value`` is not ``None`` and `to_replace` is a string,
        the replacement will be applied in all columns of the DataFrame.

        >>> df = pd.DataFrame({'A': [0, 1, 2, 3, 4],
        ...                    'B': ['a', 'b', 'c', 'd', 'e'],
        ...                    'C': ['f', 'g', 'h', 'i', 'j']})

        >>> df.replace(to_replace='^[a-g]', value='e', regex=True)

        4  4.0  e  j

        If ``value`` is not ``None`` and `to_replace` is a dictionary, the dictionary
        keys will be the DataFrame columns that the replacement will be applied.

        >>> df.replace(to_replace={'B': '^[a-c]', 'C': '^[h-j]'}, value='e', regex=True)

        Shift data by desired number of periods along axis and replace columns with fill_value (default: None).

        Snowpark pandas does not support `freq` currently.

        Parameters
        ----------
        periods : int | Sequence[int]
            Number of periods to shift. Can be positive or negative. If an iterable of ints,
            the data will be shifted once by each int. This is equivalent to shifting by one
            value at a time and concatenating all resulting frames. The resulting columns
            will have the shift suffixed to their column names. For multiple periods, axis must not be 1.

            Snowpark pandas does not currently support sequences of int for `periods`.

        freq : DateOffset, tseries.offsets, timedelta, or str, optional
            Offset to use from the tseries module or time rule (e.g. ‘EOM’).

            Snowpark pandas does not yet support this parameter.

        axis : {0 or 'index', 1 or 'columns', None}, default None
            Shift direction.

        fill_value : object, optional
            The scalar value to use for newly introduced missing values.
            the default depends on the dtype of `self`.
            For numeric data, ``np.nan`` is used.
            For datetime, timedelta, or period data, etc. :attr:`NaT` is used.
            For extension dtypes, ``self.dtype.na_value`` is used.

        suffix : str, optional
            If str is specified and periods is an iterable, this is added after the column name
            and before the shift value for each shifted column name.

            Snowpark pandas does not yet support this parameter.

    def set_index():

        Set the DataFrame index using existing columns.

        Set the DataFrame index (row labels) using one or more existing
        columns or arrays (of the correct length). The index can replace the
        existing index or expand on it.

        Parameters
        ----------
        keys : label or array-like or list of labels/arrays
            This parameter can be either a single column key, a single array of
            the same length as the calling DataFrame, or a list containing an
            arbitrary combination of column keys and arrays. Here, "array"
            encompasses :class:`Series`, :class:`Index`, ``np.ndarray``, and
            instances of :class:`~collections.abc.Iterator`.
        drop : bool, default True
            Delete columns to be used as the new index.
        append : bool, default False
            Whether to append columns to existing index.
        inplace : bool, default False
            Whether to modify the DataFrame rather than creating a new one.
        verify_integrity : bool, default False
            Check the new index for duplicates. Otherwise, defer the check until
            necessary. Setting to False will improve the performance of this
            method.

        Returns
        -------
        DataFrame or None
            Changed row labels or None if ``inplace=True``.

        Note
        ----
        When performing ``DataFrame.set_index`` where the length of the
        :class:`DataFrame` object does not match with the new index's length,
        a ``ValueError`` is not raised. When the :class:`DataFrame` object is
        longer than the new index, the :class:`DataFrame`'s new index is filled
        with ``NaN`` values for the "extra" elements.  When the :class:`DataFrame`
        object is shorter than the new index, the extra values in the new index
        are ignored—the :class:`DataFrame` stays the same length ``n``,
        and uses only the first ``n`` values of the new index.

    def squeeze():
        """
        Squeeze 1 dimensional axis objects into scalars.

        Series or DataFrames with a single element are squeezed to a scalar.
        DataFrames with a single column or a single row are squeezed to a
        Series. Otherwise, the object is unchanged.

        This method is most useful when you don't know if your
        object is a Series or DataFrame, but you do know it has just a single
        column. In that case you can safely call `squeeze` to ensure you have a
        Series.

        Parameters
        ----------
        axis : {0 or 'index', 1 or 'columns', None}, default None
            A specific axis to squeeze. By default, all length-1 axes are
            squeezed. For `Series` this parameter is unused and defaults to `None`.

        Returns
        -------
        DataFrame, Series, or scalar
            The projection after squeezing `axis` or all the axes.

        See Also
        --------
        Series.iloc : Integer-location based indexing for selecting scalars.
        DataFrame.iloc : Integer-location based indexing for selecting Series.
        Series.to_frame : Inverse of DataFrame.squeeze for a
            single-column DataFrame.

        Examples
        --------
        >>> primes = pd.Series([2, 3, 5, 7])

        Slicing might produce a Series with a single value:

        >>> even_primes = primes[primes % 2 == 0]   # doctest: +SKIP
        >>> even_primes  # doctest: +SKIP
        0    2
        dtype: int64

        >>> even_primes.squeeze()  # doctest: +SKIP
        2

        Squeezing objects with more than one value in every axis does nothing:

        >>> odd_primes = primes[primes % 2 == 1]  # doctest: +SKIP
        >>> odd_primes  # doctest: +SKIP
        1    3
        2    5
        3    7
        dtype: int64

        >>> odd_primes.squeeze()  # doctest: +SKIP
        1    3
        2    5
        3    7
        dtype: int64

        Squeezing is even more effective when used with DataFrames.

        >>> df = pd.DataFrame([[1, 2], [3, 4]], columns=['a', 'b'])
        >>> df
           a  b
        0  1  2
        1  3  4

        Slicing a single column will produce a DataFrame with the columns
        having only one value:

        >>> df_a = df[['a']]
        >>> df_a
           a
        0  1
        1  3

        So the columns can be squeezed down, resulting in a Series:

        >>> df_a.squeeze('columns')
        0    1
        1    3
        Name: a, dtype: int64

        Slicing a single row from a single column will produce a single
        scalar DataFrame:

        >>> df_0a = df.loc[df.index < 1, ['a']]
        >>> df_0a
           a
        0  1

        Squeezing the rows produces a single scalar Series:

        >>> df_0a.squeeze('rows')
        a    1
        Name: 0, dtype: int64

        Squeezing all axes will project directly into a scalar:

        >>> df_0a.squeeze()  # doctest: +SKIP
        1
        """

    def stack():
        """
        Stack the prescribed level(s) from columns to index.

        Return a reshaped DataFrame or Series having a multi-level index with one
        or more new inner-most levels compared to the current DataFrame. The new inner-most
        levels are created by pivoting the columns of the current dataframe.
        If the columns have a single level, the output is a Series.
        If the columns have multiple levels, the new index level(s) is (are)
        taken from the prescribed level(s) and the output is a DataFrame.

        Parameters
        ----------
        level : int, str, list, default -1
            Level(s) to stack from the column axis onto the index axis,
            defined as one index or label, or a list of indices or labels.

        dropna : bool, default True
            Whether to drop rows in the resulting Frame/Series with missing values. Stacking a
            column level onto the index axis can create combinations of index and column values
            that are missing from the original dataframe.

        sort : bool, default True
            Whether to sort the levels of the resulting MultiIndex.

        future_stack : bool, default False
            This argument is ignored in Snowpark pandas.

        Returns
        -------
        DataFrame or Series
            Stacked dataframe or series.

        ambiguous: ‘infer’, bool-ndarray, ‘NaT’, default ‘raise’
            When clocks moved backward due to DST, ambiguous times may arise. For example in Central European Time (UTC+01), when going from 03:00 DST to 02:00 non-DST, 02:30:00 local time occurs both at 00:30:00 UTC and at 01:30:00 UTC. In such a situation, the ambiguous parameter dictates how ambiguous times should be handled.
            - ‘infer’ will attempt to infer fall dst-transition hours based on order
            - bool-ndarray where True signifies a DST time, False designates a non-DST time (note that this flag is only applicable for ambiguous times)
            - ‘NaT’ will return NaT where there are ambiguous times
            - ‘raise’ will raise an AmbiguousTimeError if there are ambiguous times.
        nonexistent : str, default ‘raise’
            A nonexistent time does not exist in a particular timezone where clocks moved forward due to DST. Valid values are:
            - ‘shift_forward’ will shift the nonexistent time forward to the closest existing time
            - ‘shift_backward’ will shift the nonexistent time backward to the closest existing time
            - ‘NaT’ will return NaT where there are nonexistent times
            - timedelta objects will shift nonexistent times by the timedelta
            - ‘raise’ will raise an NonExistentTimeError if there are nonexistent times.

        Returns
        -------
        Series/DataFrame
            Same type as the input.

        Raises
        ------
        TypeError
            If the TimeSeries is tz-aware and tz is not None.

        Examples
        --------
        Localize local times:

        >>> s = pd.Series(
        ...     [1],
        ...     index=pd.DatetimeIndex(['2018-09-15 01:30:00']),
        ... )
        >>> s.tz_localize('CET')
        2018-09-15 01:30:00+02:00    1
        Freq: None, dtype: int64

        Pass None to convert to tz-naive index and preserve local time:

        >>> s = pd.Series([1],
        ...             index=pd.DatetimeIndex(['2018-09-15 01:30:00+02:00']))
        >>> s.tz_localize(None)
        2018-09-15 01:30:00    1
        Freq: None, dtype: int64

        Be careful with DST changes. When there is sequential data, pandas can infer the DST time:

        >>> s = pd.Series(range(7),
        ...             index=pd.DatetimeIndex(['2018-10-28 01:30:00',
        ...                                     '2018-10-28 02:00:00',
        ...                                     '2018-10-28 02:30:00',
        ...                                     '2018-10-28 02:00:00',
        ...                                     '2018-10-28 02:30:00',
        ...                                     '2018-10-28 03:00:00',
        ...                                     '2018-10-28 03:30:00']))
        >>> s.tz_localize('CET', ambiguous='infer')  # doctest: +SKIP
        2018-10-28 01:30:00+02:00    0
        2018-10-28 02:00:00+02:00    1
        2018-10-28 02:30:00+02:00    2
        2018-10-28 02:00:00+01:00    3
        2018-10-28 02:30:00+01:00    4
        2018-10-28 03:00:00+01:00    5
        2018-10-28 03:30:00+01:00    6
        dtype: int64

        In some cases, inferring the DST is impossible. In such cases, you can pass an ndarray to the ambiguous parameter to set the DST explicitly

    def drop():
        """
        Drop specified labels from rows or columns.

        Remove rows or columns by specifying label names and corresponding
        axis, or by specifying directly index or column names. When using a
        multi-index, labels on different levels can be removed by specifying
        the level. See the `user guide <advanced.shown_levels>`
        for more information about the now unused levels.

        Parameters
        ----------
        labels : single label or list-like
            Index or column labels to drop. A tuple will be used as a single
            label and not treated as a list-like.
        axis : {0 or 'index', 1 or 'columns'}, default 0
            Whether to drop labels from the index (0 or 'index') or
            columns (1 or 'columns').
        index : single label or list-like
            Alternative to specifying axis (``labels, axis=0``
            is equivalent to ``index=labels``).
        columns : single label or list-like
            Alternative to specifying axis (``labels, axis=1``
            is equivalent to ``columns=labels``).
        level : int or level name, optional
            For MultiIndex, level from which the labels will be removed.
        inplace : bool, default False
            If False, return a copy. Otherwise, do operation
            inplace and return None.
        errors : {'ignore', 'raise'}, default 'raise'
            If 'ignore', suppress error and only existing labels are
            dropped.

        Returns
        -------
        DataFrame or None
            DataFrame without the removed index or column labels or
            None if ``inplace=True``.

        Raises
        ------
        KeyError

        normalize : bool, default False
            Return proportions rather than frequencies. Being different from native pandas,
            Snowpark pandas will return a Series with `decimal.Decimal` values.
        sort : bool, default True
            Sort by frequencies when True. Sort by DataFrame column values when False.
            When there is a tie between counts, the order is still deterministic, but

        ascending : bool, default False

        -----
        The returned Series will have a MultiIndex with one level per input
        column but an Index (non-multi) for a single label. By default, rows
        that contain any NA values are omitted from the result. By default,
        the resulting Series will be in descending order so that the first

        1  3.4  4.6

        Note that a vectorized version of func often exists, which will be much faster. You could square each number elementwise.

        >>> df.map(lambda x: x**2)
                   0          1
        0   1.000000   4.494400
        1  11.262736  20.857489

        But it’s better to avoid map in that case.

        >>> df ** 2
                   0          1
        0   1.000000   4.494400
        1  11.262736  20.857489

        To generate a permanent UDF, pass a dictionary as the `snowflake_udf_params` argument to `apply`.
        The following example generates a permanent UDF named "permanent_double":

        >>> session.sql("CREATE STAGE sample_upload_stage").collect()  # doctest: +SKIP
        >>> def double(x: float) -> float:  # doctest: +SKIP
        ...     return x * 2  # doctest: +SKIP
        ...
        >>> df.map(double, snowflake_udf_params={"name": "permanent_double", "stage_location": "@sample_upload_stage"})  # doctest: +SKIP
                 0      1
        0.0  2.000  4.240
        1.0  6.712  9.134

        You may also pass "replace" and "if_not_exists" in the dictionary to overwrite or re-use existing UDTFs.

        With the "replace" flag:

        >>> df.apply(double, snowflake_udf_params={  # doctest: +SKIP
        ...     "name": "permanent_double",
        ...     "stage_location": "@sample_upload_stage",
        ...     "replace": True,
        ... })

        With the "if_not_exists" flag:

        >>> df.apply(double, snowflake_udf_params={  # doctest: +SKIP
        ...     "name": "permanent_double",
        ...     "stage_location": "@sample_upload_stage",
        ...     "if_not_exists": True,
        ... })

        Note that Snowpark pandas may still attempt to upload a new UDTF even when "if_not_exists"
        is passed; the generated SQL will just contain a `CREATE FUNCTION IF NOT EXISTS` query
        instead. Subsequent calls to `apply` within the same session may skip this query.

        Passing the `immutable` keyword creates an immutable UDTF, which assumes that the
        UDTF will return the same result for the same inputs.

        >>> df.apply(double, snowflake_udf_params={  # doctest: +SKIP
        ...     "name": "permanent_double",
        ...     "stage_location": "@sample_upload_stage",
        ...     "replace": True,
        ...     "immutable": True,
        ... })

        Replace values where the condition is True.

        Args:
            cond: bool Series/DataFrame, array-like, or callable
                Where cond is False, keep the original value. Where True, replace with corresponding value from other.
                If cond is callable, it is computed on the Series/DataFrame and should return boolean Series/DataFrame
                or array. The callable must not change input Series/DataFrame (though pandas doesn’t check it).

            other: scalar, Series/DataFrame, or callable
                Entries where cond is True are replaced with corresponding value from other. If other is callable,

        See Also:
            DataFrame.where : Replace values where the condition is False.

        Notes:
            The mask method is an application of the if-then idiom. For each element in the calling DataFrame, if cond
            is False the element is used; otherwise the corresponding element from the DataFrame other is used. If the
            axis of other does not align with axis of cond Series/DataFrame, the misaligned index positions will be
            filled with True.

            The signature for DataFrame.where() differs from numpy.where(). Roughly df1.where(m, df2) is equivalent to
            np.where(m, df1, df2).

            For further details and examples see the mask documentation in indexing.

            The dtype of the object takes precedence. The fill value is cast to the object’s dtype, if this can be
            done losslessly.

        Examples::
        >>> df = pd.DataFrame(np.arange(10).reshape(-1, 2), columns=['A', 'B'])

        Like `DataFrame.to_pandas`, this method this methods triggers a query
        evaluation and pulls data to the local machine.

        If this dataframe has columns of `Timedelta` type or columns containing
        list objects, the interchange dataframe that this method returns will
        raise `NotImplementedError` if you try to check those columns'
        datatypes, to e.g. convert the interchange dataframe to pandas with
        `pandas.api.interchange.from_dataframe`. This limitation comes from
        pandas itself.

        Parameters
        ----------
        nan_as_null : bool, default: False
            A keyword intended for the consumer to tell the producer
            to overwrite null values in the data with ``NaN`` (or ``NaT``).
            This currently has no effect; once support for nullable extension
            dtypes is added, this value should be propagated to columns.
        allow_copy : bool, default: True
            A keyword that defines whether or not the library is allowed
            to make a copy of the data. For example, copying data would be necessary
            if a library supports strided buffers, given that this protocol
            specifies contiguous buffers. Currently, if the flag is set to ``False``
            and a copy is needed, a ``RuntimeError`` will be raised.

    def isin():
        """
        Whether each element in the DataFrame is contained in values.

        Parameters
        ----------
        values : list-like, Series, DataFrame or dict
            The result will only be true at a location if all the
            labels match. If `values` is a Series, that's the index. If
            `values` is a dict, the keys must be the column names,
            which must match. If `values` is a DataFrame,
            then both the index and column labels must match.

            Snowpark pandas assumes that in the case of values being Series or DataFrame that the index of
            values is unique (i.e., values.index.is_unique() = True)

        Returns
        -------
        DataFrame
            DataFrame of booleans showing whether each element in the DataFrame
            is contained in values.

        Examples
        --------
        >>> df = pd.DataFrame({'num_legs': [2, 4], 'num_wings': [2, 0]},
        ...                   index=['falcon', 'dog'])
        >>> df
                num_legs  num_wings
        falcon         2          2
        dog            4          0

        When ``values`` is a list check whether every value in the DataFrame
        is present in the list (which animals have 0 or 2 legs or wings)

        >>> df.isin([0, 2])
                num_legs  num_wings
        falcon      True       True
        dog        False       True

        To check if ``values`` is *not* in the DataFrame, use the ``~`` operator:

        >>> ~df.isin([0, 2])
                num_legs  num_wings
        falcon     False      False
        dog         True      False

        When ``values`` is a dict, we can pass values to check for each
        column separately:

        >>> df.isin({'num_wings': [0, 3]})
                num_legs  num_wings
        falcon     False      False
        dog        False       True

        When ``values`` is a Series or DataFrame the index and column must
        match. Note that 'falcon' does not match based on the number of legs
        in other.

        >>> other = pd.DataFrame({'num_legs': [8, 3], 'num_wings': [0, 2]},
        ...                      index=['spider', 'falcon'])
        >>> df.isin(other)
                num_legs  num_wings
        falcon     False       True
        dog        False      False

        Caution
        -------
        Snowpark pandas does not perform a check for the case that values is a DataFrame or Series nor does it check
        whether the index is unique. Snowpark pandas preserves NULL values; if the DataFrame contains NULL in
        a cell the output cell will be NULL.

    def merge():
        """
        Merge DataFrame or named Series objects with a database-style join.

        A named Series object is treated as a DataFrame with a single named column.

        The join is done on columns or indexes. If joining columns on
        columns, the DataFrame indexes *will be ignored*. Otherwise if joining indexes
        on indexes or indexes on a column or columns, the index will be passed on.
        When performing a cross merge, no column specifications to merge on are
        allowed.

        .. warning::

            If both key columns contain rows where the key is a null value, those
            rows will be matched against each other. This is different from usual SQL
            join behaviour and can lead to unexpected results.

        Parameters
        ----------
        right : DataFrame or named Series
            Object to merge with.
        how : {'left', 'right', 'outer', 'inner', 'cross'}, default 'inner'
            Type of merge to be performed.

            * left: use only keys from left frame, similar to a SQL left outer join;
              preserve key order.
            * right: use only keys from right frame, similar to a SQL right outer join;
              preserve key order.
            * outer: use union of keys from both frames, similar to a SQL full outer
              join; sort keys lexicographically.
            * inner: use intersection of keys from both frames, similar to a SQL inner
              join; preserve the order of the left keys.
            * cross: creates the cartesian product from both frames, preserves the order
              of the left keys.
        on : label or list
            Column or index level names to join on. These must be found in both
            DataFrames. If `on` is None and not merging on indexes then this defaults
            to the intersection of the columns in both DataFrames.
        left_on : label or list, or array-like
            Column or index level names to join on in the left DataFrame. Can also
            be an array or list of arrays of the length of the left DataFrame.
            These arrays are treated as if they are columns.
        right_on : label or list, or array-like
            Column or index level names to join on in the right DataFrame. Can also
            be an array or list of arrays of the length of the right DataFrame.
            These arrays are treated as if they are columns.
        left_index : bool, default False
            Use the index from the left DataFrame as the join key(s). If it is a
            MultiIndex, the number of keys in the other DataFrame (either the index
            or a number of columns) must match the number of levels.
        right_index : bool, default False
            Use the index from the right DataFrame as the join key. Same caveats as
            left_index.
        sort : bool, default False
            Sort the join keys lexicographically in the result DataFrame. If False,
            the order of the join keys depends on the join type (how keyword).
        suffixes : list-like, default is ("_x", "_y")
            A length-2 sequence where each element is optionally a string
            indicating the suffix to add to overlapping column names in
            `left` and `right` respectively. Pass a value of `None` instead
            of a string to indicate that the column name from `left` or
            `right` should be left as-is, with no suffix. At least one of the
            values must not be None.
        copy : bool, default True
            This argument is ignored in Snowpark pandas.
        indicator : bool or str, default False
            If True, adds a column to the output DataFrame called "_merge" with
            information on the source of each row. The column can be given a different
            name by providing a string argument. The column will have a Categorical
            type with the value of "left_only" for observations whose merge key only
            appears in the left DataFrame, "right_only" for observations
            whose merge key only appears in the right DataFrame, and "both"
            if the observation's merge key is found in both DataFrames.

        validate : str, optional
            This argument is not yet supported in Snowpark pandas.

        Returns
        -------
        DataFrame
            A DataFrame of the two merged objects.

    def to_csv():
        """
        Write object to a comma-separated values (csv) file. This can write csv file
        either to local filesystem or to snowflake stage. Filepath staring with `@` is
        treated as snowflake stage location.

        Note: Writing to local filesystem supports all parameters but writing to
        snowflake stage does not support float_format, mode, encoding, quoting,
        quotechar, lineterminator, doublequote and decimal parameters. Also when
        writing to snowflake stage, chuncksize, errors and storage_options parameters
        are ignored.

        Parameters
        ----------
        path_or_buf : str, path object, file-like object, or None, default None
            String, path object (implementing os.PathLike[str]), or file-like
            object implementing a write() function. If None, the result is
            returned as a string. If a non-binary file object is passed, it should
            be opened with `newline=''`, disabling universal newlines. If a binary
            file object is passed, `mode` might need to contain a `'b'`.
        sep : str, default ','
            String of length 1. Field delimiter for the output file.
        na_rep : str, default ''
            Missing data representation.
        float_format : str, Callable, default None
            Format string for floating point numbers. If a Callable is given, it takes
            precedence over other numeric formatting parameters, like decimal.
        columns : sequence, optional
            Columns to write.
        header : bool or list of str, default True
            Write out the column names. If a list of strings is given it is
            assumed to be aliases for the column names.
        index : bool, default True
            Write row names (index).
        index_label : str or sequence, or False, default None
            Column label for index column(s) if desired. If None is given, and
            `header` and `index` are True, then the index names are used. A
            sequence should be given if the object uses MultiIndex. If
            False do not print fields for index names. Use index_label=False
            for easier importing in R.
        mode : {{'w', 'x', 'a'}}, default 'w'
            Forwarded to either `open(mode=)` or `fsspec.open(mode=)` to control
            the file opening. Typical values include:

            - 'w', truncate the file first.
            - 'x', exclusive creation, failing if the file already exists.
            - 'a', append to the end of file if it exists.
        encoding : str, optional
            A string representing the encoding to use in the output file,
            defaults to 'utf-8'. `encoding` is not supported if `path_or_buf`
            is a non-binary file object.
        compression : str or dict, default 'infer'
            For on-the-fly compression of the output data. If 'infer' and '%s' is
            path-like, then detect compression from the following extensions: '.gz',
            '.bz2', '.zip', '.xz', '.zst', '.tar', '.tar.gz', '.tar.xz' or '.tar.bz2'
            (otherwise no compression).
            Set to ``None`` for no compression.
            Can also be a dict with key ``'method'`` set
            to one of {``'zip'``, ``'gzip'``, ``'bz2'``, ``'zstd'``, ``'xz'``, ``'tar'``} and
            other key-value pairs are forwarded to
            ``zipfile.ZipFile``, ``gzip.GzipFile``,
            ``bz2.BZ2File``, ``zstandard.ZstdCompressor``, ``lzma.LZMAFile`` or
            ``tarfile.TarFile``, respectively.
            As an example, the following could be passed for faster compression and to create
            a reproducible gzip archive:
            ``compression={'method': 'gzip', 'compresslevel': 1, 'mtime': 1}``.

            Note: Supported compression algorithms are different when writing to
            snowflake stage.
            Please refer to https://docs.snowflake.com/en/sql-reference/sql/copy-into-table#type-csv
            for supported compression algorithms.
        quoting : optional constant from csv module
            Defaults to csv.QUOTE_MINIMAL. If you have set a `float_format`
            then floats are converted to strings and thus csv.QUOTE_NONNUMERIC
            will treat them as non-numeric.
        quotechar : str, default '\"'
            String of length 1. Character used to quote fields.
        lineterminator : str, optional
            The newline character or character sequence to use in the output
            file. Defaults to `os.linesep`, which depends on the OS in which
            this method is called ('\\n' for linux, '\\r\\n' for Windows, i.e.).
        chunksize : int or None
            Rows to write at a time.
        date_format : str, default None
            Format string for datetime objects.
        doublequote : bool, default True
            Control quoting of `quotechar` inside a field.
        escapechar : str, default None
            String of length 1. Character used to escape `sep` and `quotechar`
            when appropriate.
        decimal : str, default '.'
            Character recognized as decimal separator. E.g. use ',' for
            European data.
        errors : str, default 'strict'
            Specifies how encoding and decoding errors are to be handled.
            See the errors argument for :func:`open` for a full list
            of options.
        storage_options : dict, optional
            Extra options that make sense for a particular storage connection, e.g.
            host, port, username, password, etc. For HTTP(S) URLs the key-value pairs
            are forwarded to ``urllib.request.Request`` as header options. For other
            URLs (e.g. starting with "s3://", and "gcs://") the key-value pairs are
            forwarded to ``fsspec.open``. Please see ``fsspec`` and ``urllib`` for more
            details, and for more examples on storage options refer `here

        >>> from pathlib import Path  # doctest: +SKIP
        >>> filepath = Path('folder/subfolder/out.csv')  # doctest: +SKIP
        >>> filepath.parent.mkdir(parents=True, exist_ok=True)  # doctest: +SKIP
        >>> df.to_csv(filepath)  # doctest: +SKIP

        >>> import os  # doctest: +SKIP
        >>> os.makedirs('folder/subfolder', exist_ok=True)  # doctest: +SKIP
        >>> df.to_csv('folder/subfolder/out.csv')  # doctest: +SKIP
        """

    def to_excel():
        """
        Write object to an Excel sheet.

        To write a single object to an Excel .xlsx file it is only necessary to specify a target file name. To write to multiple sheets it is necessary to create an ExcelWriter object with a target file name, and specify a sheet in the file to write to.

        Multiple sheets may be written to by specifying unique sheet_name. With all data written to the file it is necessary to save the changes. Note that creating an ExcelWriter object with a file name that already exists will result in the contents of the existing file being erased.

        Parameters
        ----------
        excel_writer : path-like, file-like, or ExcelWriter object
            File path or existing ExcelWriter.

        sheet_name : str, default ‘Sheet1’
            Name of sheet which will contain DataFrame.

        na_rep : str, default ‘’
            Missing data representation.

        float_format : str, optional
            Format string for floating point numbers. For example float_format="%.2f" will format 0.1234 to 0.12.

        columns : sequence or list of str, optional
            Columns to write.

        header : bool or list of str, default True
            Write out the column names. If a list of string is given it is assumed to be aliases for the column names.

        index : bool, default True
            Write row names (index).

        index_label : str or sequence, optional
            Column label for index column(s) if desired. If not specified, and header and index are True, then the index names are used. A sequence should be given if the DataFrame uses MultiIndex.

        startrow : int, default 0
            Upper left cell row to dump data frame.

        startcol : int, default 0
            Upper left cell column to dump data frame.

        engine : str, optional
            Write engine to use, ‘openpyxl’ or ‘xlsxwriter’. You can also set this via the options io.excel.xlsx.writer or io.excel.xlsm.writer.

        merge_cells : bool, default True
            Write MultiIndex and Hierarchical Rows as merged cells.

        inf_rep : str, default ‘inf’
            Representation for infinity (there is no native representation for infinity in Excel).

        freeze_panes : tuple of int (length 2), optional
            Specifies the one-based bottommost row and rightmost column that is to be frozen.

        storage_options : dict, optional
            Extra options that make sense for a particular storage connection, e.g. host, port, username, password, etc. For HTTP(S) URLs the key-value pairs are forwarded to urllib.request.Request as header options. For other URLs (e.g. starting with “s3://”, and “gcs://”) the key-value pairs are forwarded to fsspec.open. Please see fsspec and urllib for more details, and for more examples on storage options refer here.

        engine_kwargs : dict, optional
            Arbitrary keyword arguments passed to excel engine.

        --------
        to_csv
            Write DataFrame to a comma-separated values (csv) file.

        ExcelWriter
            Class for writing DataFrame objects into excel sheets.

        read_excel

        read_csv
            Read a comma-separated values (csv) file into DataFrame.

        io.formats.style.Styler.to_excel
            Add styles to Excel sheet.

        Notes
        -----
        For compatibility with to_csv(), to_excel serializes lists and dicts to strings before writing.

        Once a workbook has been saved it is not possible to write further data without rewriting the whole workbook.

        Examples
        --------
        Create, write to and save a workbook:

        >>> df1 = pd.DataFrame([['a', 'b'], ['c', 'd']],
        ...                    index=['row 1', 'row 2'],
        ...                    columns=['col 1', 'col 2'])
        >>> df1.to_excel("output.xlsx")  # doctest: +SKIP

        To specify the sheet name:

        >>> df1.to_excel("output.xlsx",
        ...              sheet_name='Sheet_name_1')  # doctest: +SKIP

        If you wish to write to more than one sheet in the workbook, it is necessary to specify an ExcelWriter object:

        >>> df2 = df1.copy()
        >>> with pd.ExcelWriter('output.xlsx') as writer:
        ...     df1.to_excel(writer, sheet_name='Sheet_name_1')  # doctest: +SKIP
        ...     df2.to_excel(writer, sheet_name='Sheet_name_2')  # doctest: +SKIP

        ExcelWriter can also be used to append to an existing Excel file:

        >>> with pd.ExcelWriter('output.xlsx',
        ...                     mode='a') as writer:
        ...     df1.to_excel(writer, sheet_name='Sheet_name_3')  # doctest: +SKIP

        To set the library that is used to write the Excel file, you can pass the engine keyword (the default engine is automatically chosen depending on the file extension):

        >>> df1.to_excel('output1.xlsx', engine='xlsxwriter')  # doctest: +SKIP
