class SkillMixin():
    def __init__(self, skill):
        self.__skill = skill
    
    def get_skill(self):
        return self.__skill
        
class BasketballMixin(SkillMixin):
    def __init__(self):
        super(BasketballMixin, self).__init__('basketball') #这里会报参数错误 why？

class FootballMixin(SkillMixin):
    def __init__(self):
        super(FootballMixin, self).__init__('football')
        
class BasketballAndFootball (BasketballMixin, FootballMixin):
    def __init__(self):
        super(BasketballAndFootball, self).__init__()
   
s1 = BasketballMixin()      
s2 = BasketballAndFootball()

注释的地方会报错 提示只有1个参数但是给了两个

不符合原题目，但是不懂这里为啥会报错
