Here is what I have:

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!]

students = [lloyd, alice, tyler]

def average(numbers):

`return float(sum(numbers)) / (len(numbers))`

def get_average(students):

for x in students:

homework = average(students["homework"])

quizzes = average(students["quizzes"])

tests = average(students["tests"])

WA = (.1 * homework) + (.3 * quizzes) + (.6 * tests)

return WA

def get_letter_grade(score):

score = get_average(students)

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 x in students:

results.append(get_average(x))

return average(results)

average = get_class_average(students)

print average

print get_letter_grade(average)

Something is broken, but I can't find where though. Any advice?
