Get_class_average returns the wrong value


#1



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

The only error that I can see with my code is that it doesn't output the correct answer as stated in the following message: get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected

I instead expect it to return the correct answer as when I print get_average([alice]) I get the expected answer of 91.15.


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!
group=[lloyd,alice,tyler]
def average(numbers):
    total = sum(numbers)
    total = total/float(len(numbers))
    return total
def get_average(student):
    homework = average(student["homework"])
    quiz = average(student["quizzes"])
    tests = average(student["tests"])
    weighted_average = (0.1*homework) + (0.3*quiz) + (0.6*tests)
    return weighted_average
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 aclass:
        results.append(get_average(student))
    return average(results)

for student in aclass:

should be:

for student in students:
