There are several ways to assign values to class variables in Python.<\/p>\n

    \n
  1. Directly assigning in class definition: It is possible to directly assign values to class variables within the class definition, typically placing the assignment statement outside of class methods.<\/li>\n<\/ol>\n
    class<\/span> MyClass<\/span>:\r\n    class_var = \"Hello\"<\/span>\r\n\r\nprint<\/span>(MyClass.class_var)  # \u8f93\u51fa: Hello<\/span>\r\n<\/code><\/pre>\n
      \n
    1. Assigning values dynamically by class name: It is possible to assign values to class variables using the class name, which can be done outside of the class definition or within class methods.<\/li>\n<\/ol>\n
      class<\/span> MyClass<\/span>:\r\n    pass<\/span>\r\n\r\nMyClass.class_var = \"Hello\"<\/span>\r\nprint<\/span>(MyClass.class_var)  # \u8f93\u51fa: Hello<\/span>\r\n<\/code><\/pre>\n
        \n
      1. Clear screen.<\/li>\n<\/ol>\n
        class<\/span> MyClass<\/span>:\r\n    class_var = \"Hello\"<\/span>\r\n\r\n    @classmethod<\/span>\r\n    def<\/span> set_var<\/span>(cls, value<\/span>):\r\n        cls.class_var = value\r\n\r\nprint<\/span>(MyClass.class_var)  # \u8f93\u51fa: Hello<\/span>\r\nMyClass.set_var(\"World\"<\/span>)\r\nprint<\/span>(MyClass.class_var)  # \u8f93\u51fa: World<\/span>\r\n<\/code><\/pre>\n
        It is important to note that when accessing and assigning class variables using ‘self’ in instance methods, it actually creates an instance variable rather than modifying the class variable’s value.<\/p>\n
        class<\/span> MyClass<\/span>:\r\n    class_var = \"Hello\"<\/span>\r\n\r\n    def<\/span> set_var<\/span>(self, value<\/span>):\r\n        self.class_var = value\r\n\r\nobj = MyClass()\r\nprint<\/span>(obj.class_var)  # \u8f93\u51fa: Hello<\/span>\r\nobj.set_var(\"World\"<\/span>)\r\nprint<\/span>(obj.class_var)  # \u8f93\u51fa: World<\/span>\r\nprint<\/span>(MyClass.class_var)  # \u8f93\u51fa: Hello<\/span>\r\n<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"
