<In what way does your code behave incorrectly? Include ALL error messages.>

Hello! I was hoping someone might be able to pick out why I am receiving this error message

“Oops, try again. get_class_average([alice]) resulted in an error: list indices must be integers, not str”

I’m thinking it may have to do with something earlier in my code so I linked it all below. Any feedback would help.

<What do you expect to happen instead?>

```python 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)/len(numbers)

return total

def get_average(student):

homework = average(student[“homework”])

quizzes = average(student[“quizzes”])

tests = average(student[“tests”])

return (homework *.10) + (quizzes *.3) + (tests *.6)

results=

results.append(get_average(student))
