    this; your code should not rely on a temporary file created using this
    function having or not having a visible name in the file system.
 
-   The resulting object can be used as a :term:`context manager` (see
-   :ref:`tempfile-examples`).  On completion of the context or

    The *mode* parameter defaults to ``'w+b'`` so that the file created can
    be read and written without being closed.  Binary mode is used so that it
