Answer 1

Here is a more concise method, that does bounds checking, and will list valid values in help:

parser = argparse.ArgumentParser(description='This is a demo.')
parser.add_argument("-l", "--log", dest="logLevel", choices=['DEBUG', 'INFO', 'WARNING', 'ERROR', 'CRITICAL'], help="Set the logging level")

args = parser.parse_args()
if args.logLevel:
    logging.basicConfig(level=getattr(logging, args.logLevel))

Usage:

demo.py --log DEBUG
