    Oops, try again.
    get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected

Hi @devrunner22165 ,

You have this for loop:

for student in students:
        results.append(get_average(student))
        return average(results)

Is there a statement in that loop that should actually be outside the loop, so that it executes only after the loop has completed all its iterations?

thax appylpye now it works


#4

Maybe the error message should be a little clearer. I spent an hour trying to work out what the issue was based on the message.

Just a suggestion.
