'''
要用super（）的原因
python支持多继承
class SuperFun(Child, BadStuff):
    pass
'''

'''
super()和__init__搭配使用
'''

# class Child(Parent):
#
#     def __init__(self):
#         self.stuff = stuff
#         super(Child, self).__init__()
#  组合

    def override(self):

    def implicit(self):

        print("other altered()")
