defining methods in Python classes

In Python, there are two ways to define methods in a class:

1. The term used in programming languages to define a function.
2. oneself

class MyClass:
    def my_method(self, arg1, arg2):
        # 方法实现
        pass

1. static method
2. clear screen

class MyClass:
    @classmethod
    def my_class_method(cls, arg1, arg2):
        # 方法实现
        pass

It is important to note that class methods cannot directly access instance variables because class methods are associated with the class, not with instances. If you need to access instance variables in a class method, you can create an instance object first and then access the instance variables through that object.

Moreover, Python also supports defining static methods using the @staticmethod decorator. Static methods do not have a direct relationship with classes and instances, and can be called through the class name or instance object.

class MyClass:
    @staticmethod
    def my_static_method(arg1, arg2):
        # 方法实现
        pass

This allows you to define class methods in Python. Depending on the actual requirements, you can choose the appropriate method type to implement the functionality of the class.
