I'm not too sure where I'm going wrong here..

I keep getting the error "Oops, try again. get_average(alice) returned None instead of the expected 91.15"

alice is present and defined so I dont understand why it is pulling none instead of 91.15...

```
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 = float(total)/len(numbers)
return total
def get_average(student):
homework = average(student["homework"]),
quizzes = average(student["quizzes"]),
tests = average(student["tests"]),
0.1 * average(student["homework"]) + \
0.3 * average(student["quizzes"]) + \
0.6 * average(student["tests"])
```
