Not the best practice as any other errors that are not due to IndexErrors will still return -1. Its best to return -1 ONLY when index is out of range.

probably you are using recursive functions rigth ? it happens because all code languages can handle only a certain amount of functions during the execution and your code have probably surpassed this number.

I passed all 12 tests but there is 1 exit code error:

Traceback (most recent call last):
File "main.py", line 46, in
Test.assert_equals(doubles(arry),expected)
:
:
:
RecursionError: maximum recursion depth exceeded in comparison

What is happening?

cw's github repo, I guess. You can try, but...

Where can I ask an admin for rank change?

nope, only an admin can do that

edit: additionnal info about "local definitions":

• moderators are more or less what we call power users (PU), here
• amdin are... admins... and are the only ones who have a mod written next to their pseudo, when readin a message in the discourse (=> kazk/jhoffner, afaik)

So is there a way a codewars moderator could change the rank? This isn't a 6 kyu kata at all.

Meh

I agree with that. But thanks to some PUs who are ranking the number of chars more than the complexity of the way to come up with the solution, averages were far lower than this when I approved it, unfortunately... (errr if I'm the one who approved it...? Not sure anymore... But the answer will stay the same)

edit: the ranks aren't modifiable anymore, after approval (not by users, at least).

Hey, how is the rang of the kata decided?

I think this kata should be 5yu

I passed the sample tests but when I press attempt, it shows Response received but no data was written to STDOUT or STDERR. I'm coding in Python. Help!

I get the error on the last test: 583333333333333199654186882007384351197353825559163647809919463614194707991625728 should equal 583333333333333333333333333333333333333291666666666666666666666666666666666666668.

Is it due to a rounding error?
