def average(numbers):

total = total / len(numbers)
if score >= 90.0:
return "A"

elif score >= 60.0:
return "D"
else:
return "F"

I just don't understand where I went wrong.

#2

here:

``print get_letter_grade(average(lloyd))``

average() is a function you build to get the average of a list of numbers, are you sure you not indented to use get_average here? which calculate a student average grade

#3

I did that, and I get this error:
Traceback (most recent call last):
File "python", line 37, in
NameError: name 'get_average' is not defined

#4

you build get average in the previous exercise, where did it go?

#5

Oh, for some reason it skipped that exercise, I'll do it and try again, thanks!

#6

don't skip in this section (students become teachers), everything you build you need in the final exercise

#7

Added get average, works now, thanks for the help!
