Not sure what you mean here. The input() function always returns a
string, even if it's nothing but decimal digits.

(If you're using an ancient version of Python, then it will evaluate
the input, which would mean digits turn into an integer, but other
things will just error out - they won't be strings. Also, all the
f-strings in the OP's code wouldn't work, so that's irrelevant here.)
