In Python, operator overloading is achieved using: Special methods (dunder methods)Lambda functionsDecoratorsGenerators

Operator overloading in Python is achieved using special methods, also known as dunder methods. These methods allow you to define the behavior of an operator for a user-defined class. For example, you can define the behavior of the "+" operator for a class by defining a method named "add".

Lambda functions, decorators, and generators are all powerful features of Python, but they are not used for operator overloading.

Here is a step-by-step explanation:

1. Define a class: In Python, everything is an object. You can create your own new objects by defining a class.

class MyClass:
    def __init__(self, value):
        self.value = value

2. Define a dunder method: Dunder methods are special methods that start and end with double underscores. They are also known as magic methods. For operator overloading, you can define a method that corresponds to the operator. For example, for the "+" operator, you can define a method named "add".

class MyClass:
    def __init__(self, value):
        self.value = value

    def __add__(self, other):
        return self.value + other.value

3. Use the operator: Now, you can use the "+" operator with the objects of your class. Python will automatically call your "add" method.

a = MyClass(5)
b = MyClass(3)
c = a + b  # This will call the __add__ method
print(c)  # Output: 8

In this way, operator overloading is achieved in Python using special methods or dunder methods.
