Oops, try again. Did you remember to print the average of the class? It looks like "83.8666666667" wasn't printed.

I have tried many different things and cannot get rid of an error messsage

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 = (float(sum(numbers)))/len(numbers)
    return total
def get_average(student):
    homework= average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average (student["tests"])
    return homework*0.10 + quizzes*0.30 + tests*0.60
def get_letter_grade(score):
    if score >= 90:
        return "A"
    elif score >= 80 and score < 90:
        return "B"
    elif score >= 70 and score < 80:
        return "C"
    elif score >= 60 and score < 70:
        return "D"
    else:
        return "F"
    print get_letter_grade(get_average(lloyd))
def get_class_average(students):
    results = []
    for student in students:
        results.append(get_average(student))
    print results
    return average(results)
    students = [lloyd, alice, tyler]
    print get_class_average(students)
    print get_class_average(get_letter_grade(students))

The last three lines of your code, where the actual printing is taking place, are included inside of the get_class_average function. As a result they will only run if you call the function. If you move those bottom three lines to outside the function than everything should work fine.

I got it figured out. thank you again lol. taking a step away is always helpful

This code worked for me:

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) / float(len(numbers))
    return total

def get_average(student):
    lloyd_homework = average(student['homework'])
    lloyd_quizzes = average(student['quizzes'])
    lloyd_tests = average(student['tests'])
    lloyd_average_score = 0.1 * lloyd_homework + 0.3 * lloyd_quizzes + 0.6 *         lloyd_tests
    return lloyd_average_score
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'


students = [lloyd,alice,tyler]         
def get_class_average(students):
    results = []
    for student in students:
        results.append(get_average(student))
    return average(results)
    
students = [lloyd, alice, tyler]
print get_class_average(students)
print get_letter_grade(get_class_average(students))
