1.继承介绍_什么是继承_继承格式___bases__用法#1、什么继承？#I:继承是一种创建新类的方式，新建的类可称为子类或派生类，父类又可称为基类或超类，子类会遗传父类的属性#II:需要注意的是：python支持多继承#在Python中，新建的类可以继承一个或多个父类#继

面向对象编程-中面向对象三大特征：封装、继承、多态。封装：把内容封装起来便于后面的使用。对于封装来讲，就是使用__init__方法将内容封装道对象中，然后通过对象直接或者self获取被封装的内容。继承：子继承父的属性和方法。多态：所谓多态就是定义时的类型和运行时的类型不一样

面向对象编程-下1.私有化属性语法：两个下划线开头，声明该属性为私有，不能在类的外部被使用或直接访问。使用私有化属性的场景：1.把特定的一个属性隐藏起来，不让类的外部进行直接调用。2.不让属性的值随意改变。3.不让子类继承。classPerson():def__init__(self):
