Hello, I’m stuck in 11. 8. Part of Whole.

<In what way does your code behave incorrectly? Include ALL error messages.> This is my error message
“Oops, try again. get_class_average([alice]) resultou em um erro: global name ‘average’ is not defined”

<What do you expect to happen instead?>

```python

def get_class_average(students):
results =
for student in students:
results.append(get_average(student))
return average(results)

``````<do not remove the three backticks above>

I would be very grateful if someone could give me some help.``````

Hi can you post all your code?

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],

elif score >= 60:
return “D”
else:
return “F”

def get_class_average(students):
results =
for student in students:
results.append(get_average(student))
return average(results)

In your code it’s missing the function average from lesson It’s Okay to be Average
this one

``````# Add your function below!
def average(numbers):
total = sum(numbers)
total = float(total)

``````

Thanks! Now there’s another error message.
Oops, tente outra vez. get_class_average([alice, lloyd]) retornou 91.15 em vez de 85.85 como esperado
