Oops, try again. get_class_average([alice]) returned 87.6166666667 instead of 91.15 as expected

Oops, try again. get_class_average([lloyd]) returned 87.6166666667 instead of 80.55 as expected

# Add your function below!

    total = float(sum(numbers)) / len(numbers)
    return total

    return 0.1 * homework + 0.3 * quizzes + 0.6 * tests

    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))

students = [lloyd, alice, tyler]

results = []

def get_class_average(students):
    for student in students:
        get_average(student)
        results.append(get_average(student))
    return average(results)

print get_class_average([alice])
print get_class_average([lloyd])


#2

Problem is solved, results = [] must be replaced into the function body get_class_average.


#3

Can you write "solved" in the topic title, so everyone knows you do not need further help?
