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()
