Python the 8th time----class

1. Classes wrap functions and data neatly together

2. In object-oriented programming, you write classes that represent things and scenarios in the real world and create objects based on those classes

3. Creating an object based on a class is called instantiation, which allows you to use an instance of the class

4. A set of data and the method that processes them (object), the object of the same behavior is summed up as Class (class), and the inner details are hidden through the encapsulation (encapsulation) of the class;

Implementation of the specialization (specialization)/generalization (generalization) of the class through inheritance, and dynamic dispatch based on the object type through polymorphism (polymorphism)

5. Python is the only strategic positioning in many mainstream languages, and always adhere to the original strategic positioning of the non-wavering language

9. Class--Instance--function (method)--module
