This sounds very good to me. Might also want action='store_capture' for a single positional definition? capture could be a string, or any iterable of strings (tuple comes to mind) capture_once have similar value as capture, but I wonder if the naming would be better as capture_reset to indicate the value is reset to default, rather than just captured. Tadek said: There could be new predefined action, e.g. 'extend_with_capture' (or just 'extend_capture') which could be used like this: parser.add_argument('fruits', nargs='*', action='extend_capture', capture_once=['color']) Where 'capture' would be one of: a list of parameters to capture (could be a string instead of a list if it's just one parameter) or '*' to capture all optional parameters and 'capture_once' would be similar list of parameters to capture and reset to default. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42973> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
