In my example I pasted, I had hardcoded arguments: ``` pprint.pprint(parser.parse_args(['--ptz-get-status'])) `` I expected `python myscript.py --ptz-get-status` to work, because default value is set. I do not compute that "With one flag but not its argument", sorry. It has default argument set, shoudn't that work?
