Oops, try again. get_class_average([alice,lloyd)] returned 91.15 instead of 85.85 as expected.


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) / len(numbers)
    return total
    
def get_average(student):
    homework = average(student['homework']) * 0.1
    quizzes  = average(student['quizzes']) * 0.3
    tests    = average(student['tests']) * 0.6
    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'
    
def get_class_average(students):
    results = []
    for student in students:
        results.append(get_average(student))
        return average(results)

Check the indentation on that line. It should not be inside the loop.

Thanks a lot. It was a really dumb error.
