Python基础课：多继承

class Base:
    def play(self):
        print(‘这是Base‘)

class A(Base):
    def play(self):
        print(‘这是A‘)   

class B(Base):
    def play(self):
        print(‘这是B‘)

class C(A,B):
    def play(self):
        super().play() #super(C,self).play()  两个写法，作用一样
        #D.play()
        print(‘这是C‘)

c = C()
