Oops, try again. Did you remember to print the letter grade for the class's average?

83.8666666667
B


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]
}
students = [lloyd, alice, tyler]

# Add your function below!
def average(numbers):
    total = float(sum(numbers))
    return total / len(numbers)

def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    result = 0.1 * homework + 0.3 * quizzes + 0.6 * tests
    return result

def get_letter_grade(score):
    if score >= 90:
        print "A"
    elif score >= 80:
        print "B"
    elif score >= 70:
        print "C"
    elif score >= 60:
        print "D"
    else:
        print "F"

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

result = get_class_average(students)
print result
print get_letter_grade(result)

It may be that the SCT is looking for the actual call expression...

print get_letter_grade(get_class_average(students))

Worth a try, anyway.

Thanks for quick response! Actually, tried both ways and getting the same message.

For sake of starting with a fresh namespace, refresh the page and submit again. It may work, then.

Edit

Just noticed... Use return instead of print in the get_letter_grade function.
