Explain python class methods and static methods.
Article Introduction：Class methods automatically receive classes as the first parameter, suitable for creating or operating class-level data; static methods do not bind any parameters, suitable for functions related to classes but do not need to access classes or instances. 1. Class methods are often used as alternative constructors or processing class states, such as creating objects through string parsing; 2. Static methods are used to classify ordinary functions in classes, such as verifying whether age is legal; 3. If you need to access class states, use @classmethod, if you only need to classify tool functions, use @staticmethod, and use instance methods to access instance properties.

Vue Custom Directives Creation Tutorial
Article Introduction：Custom instructions are suitable for use in scenarios where DOM is directly operated, such as automatic focus of input boxes, permission control, lazy loading of pictures, etc. Common scenarios include: 1. The input box automatically gets focus; 2. The permission control button is displayed or disabled; 3. The implementation of lazy loading or animation triggering; 4. The numerical formatting display. It can be registered globally or locally when creating, and the commonly used hooks are inserted and updated. For example, the permission directive v-permission can control whether the element is displayed according to the user role. When using it, you should pay attention to combining binding.value parameters and executing logic in appropriate hooks, while avoiding abuse to maintain data-driven principles.
