python 继承基础

 class annamal:
     def chi(self):
         print(self.name + '吃')
     def he(self):
         print(self.name + '喝')

 class dog(annamal):
     def __init__(self,name):
         self.name = name
     def bark(self):
         print(self.name+' auhhh...')
 pp = dog('AA')
 pp.chi()
 pp.he()
 pp.bark()

python 多继承

 class Alex:
     def f1(self):
         print('alex')

 class A(Alex):
     def f(self):
         print('A')
 class B(Alex):
     def f(self):
         print('B')
 class C(A):
     def f(self):
         print('C')
 class D(B):
     def f(self):
         print('D')
 class E(C,D):
     def f(self):
         print('E')
 obj = E()
 obj.f1()
