Once your script acquires the logger object, you need to remove all the excess handlers from logger.handlers. logging.getLogger is handing you back the same object each time, and you are probably adding handlers to it -- either check to see if handlers already exist in the logging.handlers list, or do something like while len(logger.handlers()) > 0: logger.pop() before doing your custom setup.
