# Lesson 9 How is everyone doing?

#1

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],
"tests": [75.0, 90.0]
}
alice = {
"name": "Alice",
"homework": [100.0, 92.0, 98.0, 100.0],
"quizzes": [82.0, 83.0, 91.0],
"tests": [89.0, 97.0]
}
tyler = {
"name": "Tyler",
"homework": [0.0, 87.0, 75.0, 22.0],
"quizzes": [0.0, 75.0, 78.0],
"tests": [100.0, 100.0]
}

def average(numbers):
total = sum(numbers)
total = float(total)

def get_average(student):
homework = average(student["homework"]) * 0.1
quizzes = average(student["quizzes"]) * 0.3
tests = average(student["tests"]) * 0.6
return homework + quizzes + tests

if score >= 90:
return "A"
elif score >= 80:
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
else:
return "F"

def get_class_average(students):
results = []
for student in students:
results.append(get_average(student))
return average(results)

print 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!
