File Name Parsing

Learn to write automated tests using, e.g. the unittest module or third-party libraries like pytest. That will allow you to have confidence that your software works as intended and continues to work as you make changes to it.

The problem is that with the time I would need to spend programming an adequate test suite, is more than the time I would spend in normal troubleshooting.

For example converting 'ln,fn - Title - Series - date' to 'Ttile (Series) date - fn,ln' for nonfiction, and 'fn,ln - Title (date) _ Series' for fiction. I would need AI with Wikipedia API access to do that calibre of testing.
My greatest problems are unintended consequences of perfectly functioning code!

That the problem with algos. They cannot anticipate the black cyber-swan.
