Operator Overloading means giving extended meaning beyond their predefined operational meaning. For example operator + is used to add two integers as well as join two strings and merge two lists. It is achievable because ‘+’ operator is overloaded by int class and str class. You might have noticed that the same built-in operator or function shows different behavior for objects of different classes, this is called Operator

Operator overloading is a feature in Python that allows operators, such as +, -, *, /, %, ==, >, <, and others, to be used with objects of user-defined classes. This means that the behavior of operators can be customized for objects of a specific class, allowing for more intuitive and natural syntax.

In Python, operator overloading is achieved by defining special methods in a class that correspond to the desired operator. For example, to overload the + operator, the add() method needs to be defined in the class. When an object of that class is used with the + operator, Python will call the add() method with the object and the value being added as arguments.

Here is an example of operator overloading in Python: 

class Point:
    def __init__(self, x, y):
        self.x = x
        self.y = y
    
    def __add__(self, other):
        return Point(self.x + other.x, self.y + other.y)
    
p1 = Point(1, 2)
p2 = Point(3, 4)
p3 = p1 + p2
print(p3.x, p3.y)  # output: 4 6

In this example, the Point class overloads the + operator by defining the add() method, which returns a new Point object with the x and y values of the two points added together. The result is a new Point object representing the sum of the two points.
