Define

1. Static methods can also be called directly through the class name without creating an object first. The difference is that the first parameter of a class method is the class itself (cls), while static methods do not have such parameters.

If a method needs to interact with other class properties or class methods, it can be defined as a class method; if a method does not need to interact with other class properties or class methods, it can be defined as a static method.

2. When defining a static method, you need to add the decorator @ staticmethod in front of the method.

Class class: @ staticmethod def static method (): pass

Example

Import random class Char: letters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ' digits =' 0123456789' @ classmethod def random_letter (cls): return random.choice (cls.letters) @ classmethod def random_digits (cls): return random.choice (cls.digits) @ staticmethod def random_char (string): if not isinstance (string) Str): raise TypeError ('string parameter required') return random.choice (string) so far I believe you have a deeper understanding of "how to define python static methods", so you might as well do it in practice.
