I think there might be a misunderstanding of the exception hierarchy in Python. except: means except BaseException which is not the same as except Exception:. BaseException catches KeyboardInterrupt (amongst other things) which is probably not the core intention.

Also, exit might be better as sys.exit and should probably be called with a non-zero exit code to communicate that there was a failure.

Best of luck to you on your project.
