如何更新print_quiz_averages功能，以便一次打印每个人的所有分数，而不是显示每个人的每个项目的分数？

from __future__ import division

def main():
    quiz_averages = quiz_average(remove_zeros([57,0,36,29,38,31,33,0,42,0,52,28,0,50,26,97,80,63,8,36,33,39,12,36,12,59,75,61,57,39,18,9,19,35,75,5,18,0,56,0,24,0,9],
                                              [83,0,64,45,66,82,52,0,43,0,53,49,43,82,44,74,74,58,52,52,60,18,24,34,19,42,72,65,79,99,75,24,35,70,74,43,55,0,82,0,34,0,22],
                                              [69,0,38,16,16,16,55,0,28,0,44.5,31,0,33,52,75,46,33,36,0,49,34.5,35,79.5,13,27,31,52,40.5,64.5,15,0,31,47,26,0,36,0,68,0,64.5,0,20],
                                              [86,0,95,74,90,53,32,0,79,0,38,63,0,42,61,0,0,70,62,78,0,60,47,89,75,62,84,62,71,80,73,0,31,25,74,0,77,0,90,0,78,0,25]))
    student_quiz_scores = {'Raven':[61,65,52,62],

    print_quiz_averages(student_quiz_scores,quiz_averages)

def quiz_average(all_quizzes):
    averages = []
    for each_quiz in all_quizzes:
        each_average = find_average(each_quiz)
        averages.append(each_average)
    return averages

def print_quiz_averages(student_quiz_scores,the_averages):
    for i, average in enumerate(the_averages):
        print "\nThe average for quiz",i+1,"is:",average
        for student, student_data in student_quiz_scores.iteritems():
            if student_data[i]>average:
                print student, "got a",student_data[i],"which is",(str(student_data[i]-average))+"%", "higher than the average. :)"
            else:
                print student, "got a", student_data[i], "which is", (str(-student_data[i]+average))+"%", "lower than the average. :("

if __name__ == '__main__':
    main()

@adil所说的 - 切换你的嵌套循环。使用上面的代码示例......

for student, student_data in student_quiz_scores.iteritems():
    for i, average in enumerate(the_averages):
        print "\nThe average for quiz",i+1,"is:",average
        if student_data[i]>average:
            print student, "got a",student_data[i],"which is",(str(student_data[i]-average))+"%", "higher than the average. :)"
        else:
            print student, "got a", student_data[i], "which is", (str(-student_data[i]+average))+"%", "lower than the average. :("

当然，如果您希望措辞与评论中的示例完全一致（以及添加空格等），则必须更改部分字符串。
