hi i get the error
Traceback (most recent call last):
File "python", line 38, in
NameError: name 'student' is not defined

in the console and i get
Did you remember to print the average of the class? It looks like "83.8666666667" wasn't printed.
in the oops try again section

i expect it to work normally

``````lloyd = {

print get_average(students)

Wait up, you seem to be missing some functions...where's `get_letter_grade` and `get_class_average`?

I see you calling them but I don't see them. Or am I looking at the wrong link here.

#3

Wait, your get_letter_grade function is calculating the average of the students again, you need to calculate the letter grade, not the average!

``````def get_letter_grade(score):
if score >= 90:
return "A"
elif score < 90 and score >= 80:
return "B"
elif score < 80 and score >= 70:
return "C"
elif score < 70 and score >= 60:
return "D"
else:
return "F"
