And I guess the bigger issue to think about is how to add this in a backwards
compatible way. I guess we could just add methods like
"set_positionals_group_name(name)" and then fiddle with
"self._positionals.title" in there. Not sure that's a great solution though -
it seems like adding one method to change just this single attribute is
overkill and not very general.
In the meantime, here's a workaround:
>>> parser = argparse.ArgumentParser(prog='PROG')
>>> parser.add_argument('--foo', required=True)
>>> parser._optionals.title = "flag arguments"
>>> parser.print_help()
usage: PROG [-h] --foo FOO
flag arguments:
-h, --help show this help message and exit
--foo FOO
I can't promise this will continue to work, since it uses the undocumented
_optionals attribute, but at least it's a way of getting something like what
you want now.
