"Oops, try again. get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected"

I can't see anything wrong with my code that would interfere with the numbers. What exactly am I doing wrong?

``````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):
total = sum(numbers)
total = float(total)

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
homework *= 0.1
quizzes *= 0.3
tests *= 0.6
return homework + quizzes + tests

if score >= 90:
return "A"
elif score >= 80:
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
else:
return "F"

results = []

def get_class_average(students):
results.append(get_average(lloyd))
results.append(get_average(alice))
results.append(get_average(tyler))
return average(results)``````

`students` (your function parameter) can be a list of one or more students, so loop over `students`, don't manually add to results. Also place results inside the function since it is part of the function

That worked, thanks!
