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]
}

# Add your function below!

    quizzes = average (student["quizzes"])
    tests = average (student["tests"])
    grade =( 0.1*homework) + (0.3*quizzes) + (0.6*tests)
    return grade

    if score >= 90:
        return "A"
    elif score>= 80:

    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)


#2

The indentation of the return statement should line up with for so it is not inside the loop.
