How do I use class methods in Python?

Class methods in Python are defined using the @classmethod decorator. They take 'cls' as the first parameter.

Can you give me an example of a class method?

Sure! Here's a simple example:

class MyClass:
    count = 0

    @classmethod
    def increment_count(cls):
        cls.count += 1

MyClass.increment_count()
print(MyClass.count)  # Output: 1

What is the difference between class methods and instance methods?

Instance methods operate on an instance of the class and take 'self' as the first parameter, while class methods operate on the class itself.

When should I use class methods?

Use class methods when you need to access or modify class state that applies across all instances, like a factory method.
