9. How is everybody doing? - non-console error


#1


The console outputs the correct answer but the automatic checker gives the error

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


Otherwise, it seems to be working.


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"])
    homework = homework * 0.1
    quizzes = quizzes * 0.3
    tests = tests * 0.6
    return homework + quizzes + 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 i in students:
        results.append(get_average(i))
    class_average = average(results)
    return class_average

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

I'm not really sure what's wrong; any help would be appreciated.


#2

in put it together you created a list with your students, this is currently missing (it should be present)


#3

I added that in, and replaced the list in the calling of get_class_average with students, and it worked; I guess the automatic checker just didn't like it not being there.

Thanks for your help!


#4

good optimization. the checker didn't like that the list was missing.
