lloyd = {
    "name": "Lloyd",
    "homework": [90.0, 97.0, 75.0, 92.0],
    "quizzes": [88.0, 40.0, 94.0],

    "name": "Alice",
    "homework": [100.0, 92.0, 98.0, 100.0],
    "quizzes": [82.0, 83.0, 91.0],
    "tests": [89.0, 97.0]
}

    "name": "Tyler",
    "homework": [0.0, 87.0, 75.0, 22.0],

# Add your function below!
def average(numbers):
    total = sum(numbers)
    total = float(total)
    total = 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
    s=homework + quizzes + tests
    return s
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 item in students:
         results.append(get_average(item))


it keeps giving this error "Oops, try again. get_class_average([alice]) should return a number"

HI it's missing the retrun statement in the function get_class_average


#3

thank you :slight_smile: :relaxed:


#4

Even with that code, adding return to the last sentence, i get the same error.


#5

I had the same problem. For the return statement - use:

return average(results)
