class Dog(Animal):

    def run(self):#改造继承的方法

        print("cat is runing!")

    def eat(self):#增加子类的方法

        print("eat mouse!")

dog1=Dog()

cat1=Cat()

dog1.run()

dog1.eat()

cat1.run()

cat1.eat()

#---------------------------------

cat is runing!

eat mouse!

Cat is running!

eat meat!

判断变量的类型：

#!/usr/bin/env python3

# -*- coding: utf-8 -*-

a=list()

#判断变量的类型

z1=isinstance(a,list)

z2=isinstance(a,tuple)

z3=isinstance(a,str)

print(z1)#T

print(z2)#F

print(z3)#F
