https://www.codecademy.com/courses/python-beginner-en-qzsCL/1/2?curriculum_id=4f89dab3d788890003000096

When I wanna save and quit this message shows up:

Oops, try again. get_average(alice) returned (0, 97.5, 256.0, 558.0) instead of the expected 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]
}

}
# Add your function below!
def average(numbers):

return float(total)/len(numbers)
def get_average(student):

return (0,1 * homework + 0,3 * quizzes + 0,6 * tests)
