帮助使用哪些功能

如何实现这一目标：

学生＆＃39;各个最高分从最高到最低。
最后是学生＆＃39;各自的平均分数从最高到最低。
学生＆＃39;按字母顺序排名最高的分数

最终产品应该是：

Highest scores in descending order:
Name1 , HiScore1
Name2 , HiScore2
Name3 , HiScore3

Highest average scores in descending order:
Name1 , AvgScore1
Name2 , AvgScore2
Name3 , AvgScore3

Alphabetical order:
Name1 , AllScores
Name2 , AllScores
Name3 , AllScores

class extractData:
    def __init__(self):
        self.student_higest_marks = {}

    def get_content(self, filename):
        f = open(filename, 'r')
        data = f.read()
        f.close()
        return data

    def get_name_marks(self, content):
        for data in content.split('\n'):
            name = data.split('=')[0]
            marks = data.split('=')[1].strip()
            if name in self.student_higest_marks:
                self.student_higest_marks[name].append(int(marks))
            else:
                self.student_higest_marks[name] = [int(marks)]
        return self.student_higest_marks

    def cal_highest_marks(self):
        print "Highest scores in descending order:"
        highest_marks =  dict((name, max(marks)) for name,marks in
                              self.student_higest_marks.items())
        return sorted(highest_marks.items(), key=operator.itemgetter(1), reverse=True)

    def alph_order(self):
        print "Alphabetical order:"
        return sorted(self.student_higest_marks.items(), key=operator.itemgetter(0))

    def cal_avg_score(self):
        print "Highest average scores in descending order:"
        avg_marks =  dict((name, reduce(lambda x,y:x+y,marks)/len(marks)) for name,marks in self.student_higest_marks.items())
        return sorted(avg_marks.items() ,key=operator.itemgetter(1), reverse=True)

calObject = extractData()
content = calObject.get_content('Test Scores Class1.txt')
calObject.get_name_marks(content)
content = calObject.get_content('Test Scores Class2.txt')
calObject.get_name_marks(content)
print calObject.alph_order()
print calObject.cal_highest_marks()
print calObject.cal_avg_score()

希望你可以循环结果。
