return total

def get_average(student):

def get_class_average(class_list):

class_list = [lloyd, alice, tyler]

results = []

for student in class_list:

results.append(get_average(student))

return average(results)

print get_letter_grade(lloyd) shows A

print get_average(alice) shows 91.5

The error message I receive is : “get_class_average([alice]) returned 80.55 instead of 91.15 as expected”

I’m not sure how to move on.

Thank you
