def _get_subactions(self):
    return self._choices_actions
choice_dict = {'status': 'Shows current status of sys', 'load':
    'Load data in DB', 'dump': 'Dump data to csv'}
parser = argparse.ArgumentParser()
a = parser.add_argument('--foo', action=NewAction, choices=choice_dict,
    help='choices help')
a.make_help()
parser.print_help()
print(parser.parse_args('--foo status'.split()))
print(parser.parse_args())
Is there a clean way to write a one-line help per choice for argparse choices?
