What are some use cases for operator overloading in Python?

Operator overloading allows you to define custom behavior for operators in your classes. Common use cases include mathematical operations, string manipulations, and comparisons.

Can you give me an example of operator overloading in a class?

Sure! For instance, you can overload the '+' operator to add two objects of a custom class. Here's a simple example:

class Vector:
    def __init__(self, x, y):
        self.x = x
        self.y = y

    def __add__(self, other):
        return Vector(self.x + other.x, self.y + other.y)

What about using operator overloading for comparison?

You can overload comparison operators like '<' or '==' by defining methods like __lt__ or __eq__. For example:

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def __lt__(self, other):
        return self.age < other.age

Are there any downsides to using operator overloading?

Yes, while operator overloading can make your code more intuitive, it can also lead to confusion if not used carefully. It's important to ensure that the overloaded operators behave in a way that users expect.
