def get_class_average(students):

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

return average(results)``````

When I submit the above code, I am told: Oops, try again.
get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected

I am a novice. Therefore, this confuses me.

Is this what you mean? If it is, it did not work. Thanks for the help though.

try moving this back one indent (4 spaces backward)
return must always be on the same indent as a "for" statement
