Its not necessary for what you are doing but it's how you'd normally

No sorry scratch that last one I was being stupid. The key is a string
but max_points is a list so the list index max_points[x] is effectively
looking for max_points[student].
def save_grades(students,filename):
out_file =
open(filename, "w")
for x in
students.keys():
out_file.w
Maybe I should use assignments instead?
