Error - oops.try again!get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected


#2

In your function get_class_average(), you need to make sure that you return outside of the for each loop, so return should be in line with for. Additionally, instead of making a new overwriting results, just return average(results).


#3

You need to include a global variable students that contains all your dictionaries because you are referring to it multiple times in your code,

students = [lloyd, alice, tyler]

This global variabe should be outside and before any of your functions. :slight_smile:
