You're welcome. Marking this as resolved, then.

@Mednoob thank you it helped me.

Code fail is because merely the chars sort appear in the code (it doesn't even matter whatever chars may directly surround them, or whether they're in a comment), same with sorted.

Meanwhile, this should (probably) stand as an issue for two reasons:

1. NameError: name 'test' is not defined means the kata needs to be Python updated (afaik).
2. Cheater. Do not use {} does not inform the user specifically of the reason for fail

@beshoynabeih try changing sorted_array to something else. I think the anti-cheat wrongly flagged your solution because of that.

I did not use any function or method

You're using something the kata considers "cheating" - probably list.append() if I had to guess. Unfortunately the error message is itself bugged. Hint: You can finish this kata with no calls to any methods other than the one you're defining, if you choose to.

I have the same problem. Have you found a solution?

I have this error??

^^^^
NameError: name 'test' is not defined

think about two pointers
