The following message is displayed when I Save & Submit the code:
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


However, the data that they wanted to be returned was returned correctly. Below you will see my code. Any help is very appreciated!


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)
    total = total/len(numbers)
    return total
    
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    return 0.1*homework + 0.3*quizzes + 0.6*tests
    
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"
        
        
def get_class_average(students):
    results = []
    for student in students:
        results.append(get_average(student))
    return average(results)
the_average = get_class_average([lloyd, alice, tyler])    
print get_class_average([lloyd, alice, tyler])
print get_letter_grade(the_average)


#2

Define students list having all dictionaries (alice,tyler,lloyd) in it. (before get_class_average())


#3

What do you mean, greentreemee? I don't understand.


#4

First instruction says this..

Finally, print out the result of calling get_class_average with your students list. Your students should be [lloyd, alice, tyler].


#5

Oh, thanks! So it would have worked in the real world, calling students instead of the list was just how they wanted it to be done, right?


#6

It worked?

yes,apart from CC, It'd have worked but CC is stubborn towards "following instructions" , :grinning:


#7

Yes, it worked. Thanks so much for your help! :smiley: :thumbsup:


#8
