I'm still learning the basics of python (and programming in general). After comparing the solutions I have for various katas to the "best" and "clever" solutions others have devised, I have no doubt that most of the code I've written is subpar. If you don't mind me asking, what would be a more performant way of approaching this problem?

I loved this kata. It's a really clever way of making sure you understand the fundamentals. I first figured out the logic needed to get the results using print on an IDE and then realized I needed actually return an output since this was a function. Luckily strings are easy to manipulate with a simple += so I didn't have to change the structure of the code.
