As an actually unseasoned Python developer, would you be so kind as to explain why the problems you see are problems and their alternatives? Particularly the first two you note.

The call to logging.basicConfig happens at import time, which could cause issues in certain scenarios. For a one-off script, it's probably fine, but for a production app, you'd probably want to set up logging during app startup from whatever your main entry point is.

The Python standard library has a configparser module, which should be used instead of custom code. It's safer and easier than manual parsing. The standard library also has a tomllib module, which would be an even better option IMO.
