The final part of the code looks like the answer I see in other answer threads here, but i get the following error:
Oops, try again. get_class_average([alice]) resulted in an error: maximum recursion depth exceeded

Does anybody know how to fix this?

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)
    return float(total) / len(numbers)

def get_average(student):
    homework = average(student["homework"]) * 0.10
    quizzes = average(student["quizzes"]) * 0.30
    tests = average(student["tests"]) * 0.60
    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"

print get_letter_grade(get_average(lloyd))

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

Hi @orzagh,

Here the get_class_average function is calling itself ...

results.append(get_class_average(student))

That is a recursion, which should not be used here. You need to call the get_average function instead.

Ah yes, now I see! Thanks!
