# Part of the Whole error

#1

Oops, try again.
get_class_average([alice]) returned 80.55 instead of 91.15 as expected

Hey all, I am looking through my code, but I can't seem to find the error for why it would be expecting one value but returning another.
Any help would be great, thanks!

``````loyd = {

Your indentation here. It looks like you should be returning the for loop.

#3

Oops, try again.
get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected

I'm up to 83.866. Progress!

Okay, sorry about that. I would have love to see your edited code though.

Set the students list outside your function also. See below for full.

``````students = [lloyd, alice, tyler]

def get_class_average(students):
results = []
for student in students:
results.append(get_average(student))
return average(results)``````

I hadn't called the list for students outside the function.

students = [lloyd, alice, tyler]
def get_class_average(students):

``````results= []
for student in students:
results.append(get_average(student))
return average(results)``````

That worked for me now. Thanks!
