your function should return instead of printing

Your function should return the result instead of printing it. Check the Codewars docs on the left.

Python:
I think I may misunderstand the instructions or how this training thing works in general. I'm getting the proper output based on what the instruction asks for but all tests are failing. This is my second kata that I've had this issue with, so maybe I'm doing something wrong?

Thanks for your contribution. Approved!

Closing for reasons mentioned above. Please re-raise it if you're still having issues.

Could you show which solution had such problems? I looked at your submitted solutions and others, and they all pass both sample and attempt tests.

It's possible that you modified sample tests by accident, causing some error. Could you confirm this? (hit the reset button and try again)

define "wrong"

maybe what you're testing locally isn't what you're failing. passing one test isn't a very strong promise of that it's going to pass all the rest.

if you describe the problem as only "wrong" then the problem may be that you're not looking at what is happening! you've got console.log for that.

if you must post code, use the spoiler tag. ideally avoid it completely.

running your code in the kata produces error messages saying that you return "undefined". what does return mean?

hmmmm

Approved

That arrays are zero-indexed, so, for an array of length 3, the valid indices are 0, 1 and 2.

what does Index 3 out of bounds for length 3 mean?

Weird, but when done it in Prolog, my solution didn't pass the Test, but I tried the Attempt anyway and it passed and I could Submit my solution. Is there a problem with the Tests? Anyone had the same issue?
