Attributes are divided into instance properties and class propertiesMethods are divided into ordinary instance methods, class methods, static methodsBoth static and class methods of Python can be accessed by a class or instance, and the difference is obvious:1) Static methods do not need to pass in the self parameter, the class method needs to pass in the CLS parameter representing this class;2) from the 1th, the static method is unable to access the
