My code returns the error "Oops, try again. get_class_average([lloyd]) returned 85.85 instead of 80.55 as expected:"

I'll be honest, I'm at a loss on this one. I've reviewed other people who've been having issues with the same one, and I don't seem to be making any of the same mistakes. I can even copy their code, make the correction that supposedly fixes it and it still fires back the same error.

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]
}

students = [lloyd, alice, tyler]

def average(numbers):
    total = sum(numbers)
    total = float(total)
    total = total / len(numbers)
    return total

def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    homework = homework * .10
    quizzes = quizzes * .30
    tests = tests * .60
    return homework + quizzes + tests

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

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

Any ideas?

The tester is sending multiple get_class_average calls to check your code, however, results seems to only reset once the code is initially executed rather than each time the function is called.

Huh. That's simple enough. Thanks!
