# Python Student becomes the Teacher 8/9

#1

Hello, I am stuck with my code - constantly getting an error message I checked the forums for the problem, but I still can’t figure out what the problem could be. Could someone please help?

My code:

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

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

students = [lloyd, alice, tyler]

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

print get_class_average(students)
``````

Error message:
get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected

Here:

``````for student in students:
results.append(get_average(student))
return average(results)
``````

A function ends the moment a `return` key is reached. The `return` statement should therefore be placed outside the `for` loop (on the same indentation level as the `for` statement itself).

Thank you very much. After 2 days I can finally move on
