I don’t get where I’m getting wrong … I 've just pass so far two tests so far

Looks pretty backwards to me.

3

it will not work properly if is inside the ‘for problem in problems loops’’, isn’t it?

4

I didn’t say to put it in the loop, I said it’s backwards. Check again what “solution” is supposed to do :wink:

5

I still don’t get it :SSSS, with a couple of adaptions I’m failing 6 tests now.
and when I try to run this on Sublime text or VSCode it’s just show the last element of the list and not the other elements

If solution is true, you should show the final line - you are doing the exact opposite.

7

oh damn… what a mistake! :slight_smile:
