我有一个脚本，可以计算课程中所有学生的所有测验，作业和考试成绩的平均值。然后，我希望它比较每个学生在每个项目上的表现与使用词典的项目的平均值相比较。我怎么能这样做？

回应关于有多少代码的评论，但这里有一个你的函数被重写，所以你可以将它推广给你的其他人：
def print_quiz_averages(student_quiz_scores,the_averages):
for i, average in enumerate(the_averages):
print "The average for quiz",i+1,"is:",i
for student, student_data in student_quiz_scores.iteritems():
if student_data[i]>average:
print("{:s} did {:.2f}% higher than average\n".format( student, student_data[i]-average))
else:
print("{:s} did {:.2f}% lower than average\n".format( student, -student_data[i]+average))
