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
