It's a horrible idea to use try/except for completely preventable exceptions.

It's slow af. Your asymptotic time complexity is just horrible... It's O(n^3).

A bad solution on this problem is normally "just" O(n²)... (my solution is O(n))

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

Thanks!

if you subtract 97 inside the first expression, yes

edit: errr... not sure what you really mean. Let's say, there is a link, yes

Because you're passing a list with a string inside there and here the input is a string. And no, it returns a list with a string inside, not a string, do you see the [] there?

What are you using that loop for? That code is not even returning a string. Do you see why it's wrong now?

Sorry, but I don't get what a is in the first code, maybe you meant s there? You're returning a list in that case and it'll break with some input value. The last code is ok.

Because you're not doing what the kata asks, read the instructions again, it is much more simpler than you think.

Also, Python code without indentation, is very hard to read, please, use markdown formatting when posting code.
