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]
}

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

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
