多态的案例演示

# pcj
class Dog(object):
    def __init__(self,name):
        self.name=name

    def run(self):
        print("%s只会普通的玩"% self.name)

class XiaoTiaoDog(Dog):
    def run(self):
        print("%s飞到天上去玩"% self.name)

class Person(object):
    def __init__(self,name):
        self.name=name

    def game_with_dog(self,dog):    #传入的是普通狗还是飞天狗，这里是关键
        print("%s和%s快乐的玩"%(self.name,dog.name))
        #让狗玩
        dog.run()
#1 创建一个狗对象
# wangcai=Dog("旺财")
wangcai=XiaoTiaoDog("飞旺财")
# 2、创建一个小明对象
xiaoming=Person("小明")

#3、让小明和狗玩的方法
xiaoming.game_with_dog(wangcai)
