Hello all! I am really confused on what I've done wrong so can someone explain to me what I've done wrong?

Error Message:
Oops, try again. One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade


lloyd = {
    "name": "Lloyd",
    "homework": [90.0, 97.0, 75.0, 92.0],
    "quizzes": [88.0, 40.0, 94.0],

    total = sum(numbers)

    return total / len(numbers)

print get_letter_ grade(get_class_average(lloyd, alice, tyler))


#2

get_class_average() takes a list. Create the list where it was created in lesson 3, just under the dictionaries.

students = [ lloyd, alice, tyler ]

#3

I still get the same error message even when I put the list. Is their anything else I could do?
Also what does the missing / broken part in the error message mean?


#4

Never mind that. I forgot to delete a space while defining get_letter_grade. Thanks for helping me twice!
