it says 'class' list. There is no so called class list that exists.
But if I take the variables into a list called class, the error comes:

File "python", line 2
lloyd: {
^
SyntaxError: invalid syntax

And if I replace it with a = sign,
File "python", line 2
lloyd = {
^
SyntaxError: invalid syntax

If I don't take them into a class list.
Oops, try again. get_class_average([alice]) resulted in an error: global name 'Class' is not defined
my code:

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)
    average = total / len(numbers)
    return average
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    return homework * 0.1 + quizzes * 0.3 + \
    tests * 0.6
def get_letter_grade(score):
    if(score >= 90):
        return "A"
    elif(80 <= score < 90):
        return "B"
    elif(70 <= score < 80):
        return "C"
    elif(60 <= score < 70):
        return "D"
    else:
        return "F"
print get_letter_grade(80.55)

    results =[]

        results.append(get_average(student))

Hi the error come from here

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

the error says global name 'Class' is not defined
because you used Class but you did create a variable with that name
here

 for student in Class:

you should instead use students like that

for student in students:
