ty @chrono79 i was wondering exactly the same thing as brazenAI

Wouldn't .casefold() be better used to check for both lower and upper?

no need to use else, just return.

whats with an empty string?

i didn't think about that

If I put spaces before the name your solution goes to shit :)

i too

i use upper :)

I assume it's not "best practice" to leave the "else" out of this? Since "return" ends the function immediately, the bottom case will only run if the "if" statement is false, barring the need for the "else". But I guess it's best practice for readability purposes.

Thanks for answering @Chrono79

Where is this code testing 'R' in the name?
Could you please explain?

it works either way
