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.

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) 
    return total/len(numbers)

Thanks! :relieved: :slight_smile: 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
