Thank you mrxinu.

A word of advice, that feeling is the first symptom of addiction to recursion, you will soon find yourself using it, and might even convert to haskell or some other weird lisp dialect.

More seriously, I'm aware of the fact that recursion is an heresy in Python.

I'm confused about how it got submitted as an answer.

As soon as I see recursion I want to vomit on my shoes. Not because it's not a clever solution but mostly because recursion makes me want to vomit on my shoes. Well done!

I knew there was a lookahead/behind play here but I couldn't make it work in my head. Really nicely done!

Best comment ever.

That was a forehead-smacking moment for sure, but truly awesome. Well done!

That's an awesome explanation. Thank you!

It's taking the stuff inside the ()'s in join() and stringing the elements in the list together with spaces.

Same, I used title() and didn't realize that was more for an entire string.

Criticism aside this is a very pretty regex.

Aren't we all? It never would have occured to me that I could alter the table. :)

I'm just learning, thanks!

Fearless! 😀

I don't think so, but it was confusing and didn't wind up having anything to do with the solution.
