一. 类 对象

class Dog():
    #初始化类的属性
    def __init__(self,name):
        #内部属性
        self.name = name
    #类内方法
    def run(self):
        print(self.name+' is running')

my_dog = Dog('Wang')
my_dog.run()

二. 继承

class Dog():
    #初始化类的属性
    def __init__(self,name):
        #内部属性
        self.name = name
    #类内方法
    def run(self):
        print(self.name+' is running')

my_dog = Dog('Wang')
my_dog.run()

class LittleDog(Dog):
    def __init__(self,name):
        super().__init__(name)
        # self.id = '0'
        self.id = "1"
    def jump(self):
        print(self.id+'\'s name is '+self.name)
