Hello,
I am getting an error telling that "Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected"

Can anyone tell me where I am going wrong in it
Thanks in advance

Please punctuate your code sample with three back-ticks, beginning and end.

```

Before and after code only. Thank you.


#3

Conspicuous by its absence,

students = [lloyd, alice, tyler]

#4

Hello,
Thank you for your help but now I have overcome from the result .there isn't any things missing, but I have included

return average(results) in if block
but thanks for your suggestion,I will remember that thing before posting any code help to include punctuate marks in future

Thanks,
Snehal

i ve the same error and i dont understand why :

def get_class_average(students):
results = []

for i in students:
    results.append(get_average(i))
    return average(results)

error:
Oops, try again.
get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected

Because you have a wrong indent in your code block. Remove a tab before you return. You want to return from the for loop.. Otherwise you return to early.
