Excuse me, but there is nothing to proud of. In exercise it put tag "ALGORITHMS", and solving it with already existed solution at least not correct to yourself. If you will always copy code from stackoverflow you will become a monkey-coder, not a programmer and definately not an engineer.
Codewars was created to challenge your mind. So where is challenge if you choose to go easy way?

Just think about it. I DO know that bussiness requiring fast and working solutions. But you have to be ready to do something from scratch, it's what makes you more valuable among thousands of monkey-coders around the world

Nice kata. For me it was much more challenging then 3-5 kyus katas that have already done. One-string solutions got me frustrated :-)

That's absolutely right, thanks.
I'm just 2 weeks learning python, and I appreciate your comment. But now I guess I would make that code more "Pythonic", like you did :-)
