在菱形多繼承中，如果用父類.__init__（）來呼叫父類的初始化方法，最上層會執行兩次，所以遇到這種情況，python中用super.__init__()來解決這個問題。

class Grand_father(object):
    def __init__(self):
        print('爺爺')


class Father_left(Grand_father):
    def __init__(self):
        super(Father_left,self).__init__()
        # Grand_father.__init__(self)
        print('左邊爸爸')


class Father_right(Grand_father):
    def __init__(self):
        super(Father_right, self).__init__()
        # Grand_father.__init__(self)
        print('右邊爸爸')


class Me(Father_right,Father_left):
    def __init__(self):
        super(Me, self).__init__()
        # Father_left.__init__(self)
        # Father_right.__init__(self)
        print('我')

def main():
    me = Me()

if __name__ == '__main__':
    main()
 

如果需要呼叫左邊爸爸，那就執行super(左邊爸爸類).
