python 面向对象 (多态)

什么是多态?多态就像是人有多种心情,场景不一样心情就会不一样.

 class Dog:

     def print_self(self):

         print('this is dog')

 class Hsq(Dog):

     def print_self(self):

         print('this is 哈士奇')

 def introduce(temp):

     temp.print_self()

 dog1 = Dog()

 dog2 = Hsq()

 introduce(dog1)

 introduce(dog2)

--->

this is dog
this is 哈士奇
