Duplicate.

yeah, accidentally i returned None when n and the list size were equal. you were right

You were returning None when a list was expected. I've fixed this, and now one will get a message directing the error rather than the apparently meaningless error log.

i solved the kata and all the tests are ok. but when i click the 'attempt' button i get this error:
Traceback (most recent call last):
File "/runner/frameworks/python/cw-2.py", line 111, in wrapper

Thank you for the quick reply and fix

Click on RESET

disregard, i think you fixed it

this is what i get on another one now. If its me plese let me know.

[407.66666666666663, 388.3333333333333, 328.6666666666667, 324.0, 392.0] should equal [407.6666666666667, 388.3333333333333, 328.6666666666667, 324.0, 392.0]

Can you please check again?

Fixing.......

Why am I getting dinged for not having enouch decimal places and rounding in my answer?

[212.0, 226.33333333333331, 240.99999999999997, 236.33333333333334, 173.66666666666666] should equal [212.0, 226.33333333333334, 241.0, 236.33333333333334, 173.66666666666666]

Updated the description to make it more readable, and approved as 7 kyu despite of average rank of 6 kyu.

7 kyu kata represent a beginner programming level. At this level the kata will generally challenge 
users on their core language and API reference knowledge. Tasks such as:

    Iterating arrays and returning a subset of values <---- which is exactly what one have to do here.
