This article describes in detail the types and inheritance relationships in Python. Share to everyone for your reference. The specific analysis is as follows: If an object a holds the ID of another object B, then a B can be retrieved after a

Objective For functional bindings (function binding) It's probably the least bit of attention when you're using JavaScript, but when you realize that you need a solution to keep this context in another function, what you really need is actually

In the implementation interface, we use the interface syntax to separate the interface from the class definition and form a body. Interface provides the interface specification for the class. In inheritance, we introduce the inheritance mechanism
