For a fast solution you can just set backspace character to a metavar.

p.add_argument('-i', '--ini', help="use alternate ini file", metavar='\b')

It will get you this:

optional arguments:
  -h, --help         show this help message and exit

If you want this:

  -i, --ini INI      use alternate ini file

You will have to modify help formatter. Answered here python argparse help message, disable metavar for short options?
