What are magic methods in Python?

Magic methods in Python are special methods that start and end with double underscores, like init and str. They allow you to define how objects behave with built-in functions.

Can you give me an example of a magic method?

Sure! The init method is a constructor that initializes an object's attributes when it's created. For example:

class Dog:
    def __init__(self, name):
        self.name = name

What does the str method do?

The str method defines how an object is represented as a string. For instance:

class Dog:
    def __str__(self):
        return f'Dog: {self.name}'

Are there any other commonly used magic methods?

Yes, other common magic methods include add for addition, len for length, and getitem for indexing.
