When should I use a class method in Python?

When should I use a class method in Python?

You should use a class method when you need to access or modify class state, rather than instance state.

Can you give me an example of a class method?

Sure! A common example is a factory method that creates an instance of the class using class-level data.

What’s the difference between a class method and a static method?

A class method takes a reference to the class as its first parameter, while a static method does not take any reference.

When would I prefer a static method over a class method?

You'd prefer a static method when you don't need to access or modify class or instance state, just utility functions.
