大佬，打印出平均分，最高，最低分的语句怎么写呀?如图!

class students:
    def __init__(self,name,hao,math,english,computer):
        self.name=name
        self.hao=hao
        self.math=math
        self.english=english
        self.computer=computer

    def score(self):
        score=self.math +self.english +self.computer
        return score
    def math(self):
        return self.math
    def english(self):
        return self.english
    def computer(self):
        return self.computer

class subject:
    def __init__(self,*students):
        self.list1=[i.math() for i in students]
        self.list2=[i.english() for i in students]
        self.list3=[i.conputer() for i in students]

    def ave(self):
        return "数学平均分{}英语平均分{}计算机平均分{}".format(sum(self.list1)/len(self.list1),sum(self.list2)/len(self.list2),sum(self.list3)/len(self.list3))

    def max(self):
        return"数学最高分{}英语最高分{}计算机最高分{}".format(max(self.list1),max(self.list2),max(self.list3))

    def min(self):
        return"数学最低分{}英语最低分{}计算机最低分{}".format(min(self.list1),min(self.list2),min(self.list3))

a=students('zhang',2000,91,96,93)
b=students('ming',2001,93,82,91)
c=students('chen',2002,86,84,93)

print("总分为:",a.score(),b.score(),c.score())
print

问题解决的话，请点下采纳
