fix: f-string expression part cannot include a backslash

[Daniel-Aaron-Bloom]

f-string and string concat is redundant and \n causes issues on older versions of python (I'm getting this on Python 3.13.5).

Traceback (most recent call last):

I would like to start by saying that I appreciate when someone takes a look at the code and I like it even more when they already provide the fixes for the problems. So, huge thanks!

The fix is rather simple and I will accept it, but first I will test it locally to see if nothing breaks unexpectedly. It also makes the code more readable (I don't know I made the code like that to be honest with you).

I'm getting this on Python 3.13.5

Well, that is interesting. I have just checked my python version (just to see why I didn't get the error) and I am actually using an older version of python (Python 3.13.1). Anyways, I will just test and implement your fix.

To finish, thanks for contributing!

It took me a while to be able to stop and test the code, but I finally got the time. The code did not break anything and was merged into the main branch.

I will do some other small updates and release a new version on Pypi.

Once again, thanks for the contribution!
