Then maybe we could just make a new function that takes 2 arguments: Name of
another action class (or the action class itself), and a tuple of the arg names
to be displayed. It returns a new action class that contains the help text
properties of the given action class with customized displayed arg names.
Maybe like
parser.add_argument("-f", "--foo",
action=argparse.CustomArgName(action="store_true", name=("-F!!", "--FOO!"),
help="TO foo a bar"))
