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

#2

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.
