Python cls

advantages of the Python static method If you don’t need access to the attributes or methods of the class or instance, a staticmethod is better than a classmethod or instancemethod . That way it is clear (from the @staticmethod decorator) that the class’ and instance’s state is not read or modified.

cls refers to the class, whereas self refers to the instance . Using the cls keyword, we can only access the members of the class, whereas using the self keyword, we can access both the instance variables and the class attributes.

Uses of classmethod() function are used in factory design patterns where we want to call many functions with the class name rather than an object .

What is a static method? Static methods, much like class methods, are methods that are bound to a class rather than its object . They do not require a class instance creation. So, they are not dependent on the state of the object.
