Here we will simply simulate the implementation of this effect.

Because Python is a dynamic language, an instance created from a class can be arbitrarily bound to a property.The way to bind properties to an instance is through an instance variable, or through a self variable:class Student(object): def __init__(self, name): self.name = names = Student(‘Bob‘)s.score = 90But what if the Student class itself needs to bind a property? You can define a property directly in class, which is a class attribute and belong

Per.age =;
Alert (Per.name + per.age);
We want to get an object variable in the program, as long as we can store a lot of data, we can consider using the object class at this time. The object class avoids the definition of a constructor.
