Given the codewars unstrictness in test cases and solution complexity, this simplicity is completely appropriate. ;-) Adding several lines to take care of edge cases is pretty obvious, but not as elegant.

Very short and cool but some cases are not totally treated efficiently as you stop at the end.

For instance : ") (a very long) (example) (and) there is also other ones..."

I know, it's difficult to have a short and efficient solution at once :-)
Mine is very long and not python oriented like yours. I prefer yours !
