多重繼承問題：super中傳一個多重繼承的類，只能識別到第一個
問題描述：
B繼承A，Y繼承Z，BY繼承B和Y，那么BY中的super只能代表B（如果是YB則只能代表Y），希望是可以super可以代表BY，代碼如下：
class SkillMixin(object):
def?init(self,skillName):
self.skillName = skillName
class BasketballMixin(SkillMixin):
def?init(self,skillName):
super(BasketballMixin,self).init(skillName)
class Person(object):
def?init(self,name,gender):
self.name = name
self.gender = gender
class Student(Person):
def?init(self,name,gender,score):
super(Student, self).init(name, gender)
self.score = score
class BasketballStudent(Student,BasketballMixin,):
def?init(self,name,gender,score,skillName):
super(BasketballStudent,self).init(name,gender,score,skillName)
bs = BasketballStudent('basketboy','man',59,'basketball')
print(bs.name,bs.skillName)

打印姓名沒問題，打印球就報錯，很好的說明了這個問題

我也發(fā)現(xiàn)這個問題，多重繼承好像是個笑話，本質(zhì)上還是只繼承了第一個
