Oops, try again. get_class_average([alice]) returned 93.0 instead of 91.15 as expected

I got an error message. Please help.


Replace this line with your code. 
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)
    total = float(total)
    n = total / len(numbers)
    return n  
    
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    return 0.1 * average(student["homework"]) + 0.3 * average(student["quizzes"]) + 0.6 * average(student["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:
        get_average(student)
        results.append(students)
        results = average(student["tests"])
        return results

this is good:

get_average(student)

now append the result of this function call to results

then after the loop, return the average of results
