"How's everyone doing?" Something missing or broken?

I keep getting this:
“Oops, try again. One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade”

But I get this as an out put:
“B
83.8666666667
B
None”

I feel like I am close but just can’t figure it on it.



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"]

def average(numbers):
    total = sum(numbers)
    total = float(total)
    Length = len(numbers)
    new = total / Length
    return new
    
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    homework = homework * .1
    quizzes = quizzes * .3
    tests = tests * .60
    tot = homework + quizzes + tests  
    return tot
    
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 student in students:
            get_average(student)
            results.append(get_average(student))
    return average(results)

print get_class_average([lloyd, alice, tyler])  
print get_letter_grade(get_class_average([lloyd, alice, tyler]))

Hi @coreninja7587,

This statement should not have quotes around the names of the three dictionaries in the list

students = ["lloyd", "alice", "tyler"]

Yes that is it! Wow, I should have known. Thank you!
