I don't understand what I did wrong...

https://www.codecademy.com/courses/python-beginner-en-qzsCL/1/2?curriculum_id=4f89dab3d788890003000096

Oops, try again. get_average(alice) raised the following error: local variable 'quizzes' referenced before assignment

I returned the sum of the averages, shouldn't it work?

Replace this line with your 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]
}
# Add your function below!
def average(numbers):
total = sum(numbers)
total = float(total)
result = total / len(numbers)
return result
def get_average(student):
homework = average(student['homework'])
quizzes = quizzes(student['quizzes'])
tests = tests(student['tests'])
return sum((homework * 0.1, quizzes * 0.3, tests * 0.6))
