Improvement: error_msg changed to f-strings

[xunzhou]

As @colin-pm suggested in #873 (comment),
updating error_msg to f-string

[colin-pm]

Awesome, thanks for going through the code and changing all the error messages! Looks good to me besides one issue at the bottom.

One extra thing that would be nice is to shorten the line length of these messages to conform to PEP-8. I think you can automate that by running --experimental-string-processing with black.

@colin-pm f-string for other strings like api_auth ?

[colin-pm]

@xunzhou The more f-strings, the better imo

The pylint errors could be fixed by running black with the --experimental-string-processing as I recommended above.

The hvac project is simplifying its developer workflow and removing the develop branch. Please be aware for future PRs that the project's default branch is now main.

Since your PR was opened before this change, I have:

• updated your PR to merge into the project's main branch

You will need to pull down the latest main branch, and then rebase your branch against main and force push:

git rebase main
git push -f

Because this PR has conflicts, I have not done the rebase myself, but if you need a hand, let me know.
