-## Map, Fileter and Reduce Functions
-
-## 1. Walrus Operator (:=)
-Introduced in Python 3.8, the walrus operator allows assignment expressions, enabling assignment and return of a value in a single expression. This is particularly useful in loops and comprehensions.
-```python
-# Not Allowed
-print(is_alive=False)
-# Allowed
-print(is_active:=True)
-```
-
-## 2. Matrix Multiplication Operator (@)
-Introduced in Python 3.5, the '@' operator is used for matrix multiplication, which is especially useful in numerical computing and machine learning applications.
-```python
-import numpy as np
-
-a = np.array([[1, 2], [3, 4]])
-b = np.array([[5, 6], [7, 8]])
-
-# Matrix multiplication
-c = a @ b
-print(c)
-```
-
-## 3. New String Formatting (f-strings)
-Introduced in Python 3.6, f-strings provide a way to embed expressions inside string literals, using curly braces '{}'.
-```python
-name = "Abhinay"
-age = 21
-print(f"My name is {name} and I am {age} years old.")
-```
-## 4. Enhanced Unpacking
-Python 3.5 introduced extended unpacking with the '*' operator to allow more flexible unpacking operations.
-```python
-a, *b, c = [1, 2, 3, 4, 5]
-print(a)  # 1
-print(b)  # [2, 3, 4]
-print(c)  # 5
-```
-## 5. Positional-Only Parameters
-Introduced in Python 3.8, positional-only parameters are defined by adding a '/' in the function signature. These parameters can only be passed positionally, not as keyword arguments.
-```python
-def greet(name, /, greeting="Hello"):
-    return f"{greeting}, {name}!"
-
-print(greet("Abhinay"))  # Works
-# print(greet(name="Abhinay"))  # Raises TypeError
-```
-
-## 6. Keyword-Only Parameters
-Defined by adding '*' in the function signature, parameters following '*' can only be passed as keyword arguments.
-```python
-def greet(*, name, greeting="Hello"):
-    return f"{greeting}, {name}!"
-
-print(greet(name="Abhinay"))  # Works
-# print(greet("Abhinay"))  # Raises TypeError
-```
-These new operators and enhancements make Python more expressive and capable of handling various programming paradigms more efficiently.
