Python Classmethod modifier

Describe

The function that corresponds to the Classmethod modifier does not need to be instantiated, does not require the self parameter, but the first parameter needs to be a CLS parameter that represents its own class, can invoke the class's properties, the class's methods, instantiate the object, and so on.
