The error I'm receiving is "get_class_average([alice]) should return a number"

I can't figure out why it would specifically tag her as the coding seems identical to Lloyd's - so presumably that one would throw the error first.

Thanks for the help.

```
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",

"quizzes": [0.0, 75.0, 78.0],
"tests": [100.0, 100.0],
