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))

if we actually add a function call:

get_average(alice)

we can see where the error originates, in this case, this line:

quizzes = quizzes(student['quizzes'])

uhm... while defining quizzes you already refering to quizzes, (second quizzes) while it doesn't exist yet, that indeed raises a error.

step 2 from the instructions:
Make a variable homework that stores the average() of student["homework"]
step 3:
Repeat step 2 for "quizzes" and "tests"
i am not sue why you stop using average, you want to get the average score of quizzes and test, and store them in a variable

Thanks a lot!
I have no idea why I stopped using average either!
