What's the point of the r? I did basically the same thing except without the r, and it worked fine.

"foobar00" turns into "foobar01" because the end result after the string was incremented was 2, which did not take up both digits. If it was "foobar09", then it would turn into "foobar10", because the result now takes up both zeros which were in the input. In the case of "foobar099", 99 turns into 100, meaning it now takes up 3 digits. In "foobar099", there are 3 numbers at the end, so you would not include the extra 0 after incrementation.

It means you didn't return anything, when you should've returned 42.

I only took a quick look, but treating an array as string looks like a bad idea IMO. Stick to something closer to arrays/lists.

i forgot to delete import statistics from a previous attempt it is not needed

ok 👍

also all identical:

• The Hashtag Generator
• Human Readable Time
• Playing with digits

perhaps a bit too friendly?

fixed

we're friends irl and i asked him to test my kata

thanks

Codewars has thorough documentation on authoring a kata, including this on Random Tests.

i don't know how tbh

no random tests
