p1多继承

创建父类：

父亲类

class Father(object):
    def _init_(self, money, play)
        self.money = money
   def play(self):
        print('play')
   def func(func1):

母亲类

class Mother(object):
    def _init_(self, facevalue):
        self.facevalue = facevalue
    def eat(self):
        print('eat')
    def func(self):
        print('func2')

创建子类：

孩子类

from Father import Father
from Mother import Mother

class Child（Father,Mother）：
    def _init_(self,money,faceValue):
        Father.__init__(self, money)
        Mother.__init__(self,faceValue)

frome Child import Child

def main():
    c = Child(300, 100)
    print(c.money, c.faceValue)
    c.play()
    c.eat()
    # 父类中方法相同，默认调用的是在括号中派前面的父类的方法
    c.func()

if __name__ == "__main__"
   main()

p2多态

class Animal(object):
    def __init__(self,name):
        self.name = name
    def eat(self):
        print(self.name + '吃')

from animal import Animal

class Cat(Animal):
   def __init__(self,name):
       super(Cat, self)__init__(name)

from animal import Animal

class Mouse(Animal):
   def __init__(self,name):
       super(Mouse, self)__init__(name)

from cat import Cat
from mouse import Mouse
from person import Person

'''
多态：一种事务的多种形态

最终目标：人可以喂任何一种动物
'''

tom = Cat('tom')
jerry = Mouse('jerry')

tom.eat()
jerry.eat()
