What's the difference between @classmethod, @staticmethod, and "plain/regular" instance methods in Python? You'll know the answer after watching this Python video tutorial:

Regular (instance) methods need a class instance and can access the instance through `self`. They can read and modify an objects state freely.

Class methods, marked with the @classmethod decorator, don't need a class instance. They can't access the instance (self) but they have access to the class itself via `cls`.

Static methods, marked with the @staticmethod decorator, don't have access to `cls` or `self`. They work like regular functions but belong to the class's namespace.

In this video tutorial I go over the differences between these different kinds of methods in Python. I also explain when to use each with a simple example so you can improve your object-oriented programming (OOP) skills in Python.
