Oops, try again. get_class_average([alice]) returned 80.55 instead of 91.15 as expected


#1

I have a question referring to the "Part of the Whole" in the exercise "Student Becomes the Teacher". I'm supposed to get the average mark of the class. However, I keep taking the error referred in the title. I've seen that there are various persons asking about the same problem but I still don't have a clear idea about why my code is failing.

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]
}

def average(numbers):
    total = sum(numbers)
    total = float(total)
    total = total / len (numbers)
    return total
    # Add your function below!
def get_average(student):
    homework = average(student['homework'])
    quizzes = average(student['quizzes'])
    tests = average(student['tests'])
    return 0.1 * homework + 0.3 * quizzes + 0.60 * 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 students in students:
        get_average(student)
        results.append(get_average(student))
    return average(results)


#2

    for singular in plural:

As in, student in students.

The second line can be removed. It is not doing anything.
