That's coming from the `metavar=""'. If I specify `metavar="xxx" that help line will have -p xxx, --projectid xxx Replace the 'xxx` with '', and you still have space between '-p' and ','. Now that I see it, it looks familiar. I noted it in passing in StackOverflow answer, http://stackoverflow.com/a/40497623/901925 I can't find a related bug/issue. It's a natural consequence of the formatting in HelpFormatter._format_action_invocation # if the Optional takes a value, format is: # -s ARGS, --long ARGS parts.append('%s %s' % (option_string, args_string)) There's no special handling for the case where ARGS is blank. That formatter method could be customized as suggested in http://stackoverflow.com/a/23941599/901925 Often people want a more compact invocation like: -s, --long ARG help Usage gets that space between option_string and args_string, but it gets striped out later. So the fix (not tested) would something like: def _format_action_invocation(self, action): .... for option_string in action.option_strings: if len(args_string)>0: parts.append('%s %s' % (option_string, args_string)) else: parts.append('%s' % option_string) .... ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29626> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
