What are the differences between class and instance methods in Python?

Can you explain the differences between class and instance methods in Python?

Sure! In Python, class methods are bound to the class and not the instance. They take 'cls' as the first parameter, while instance methods take 'self'.

What does 'cls' and 'self' mean?

'self' refers to the instance of the class, allowing access to instance variables. 'cls' refers to the class itself, allowing access to class variables.

Can you give me an example of each?

Of course! An instance method might modify instance attributes, while a class method can modify class attributes. Here's a quick example:

class MyClass:
    class_variable = 0

    def instance_method(self):
        self.instance_variable = 1

    @classmethod
    def class_method(cls):
        cls.class_variable += 1
