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

should return 85.85

Hi this line

``return average(results)``

should be indent like the for loop in the function

My code is not working . showing "Oops, try again. get_class_average([alice]) should return a number" error. Can someone help me
