paul j3 added the comment: These two types of groups serve different purposes and aren't designed to nest or interact.
An argument group groups arguments in the help lines. It does not affect parsing at all. It can't be used to add a 'group' of arguments to another group. A mutually exclusive group produces an error message during parsing, and modifies the usage line. There isn't a way, in the current code, to nest groups of arguments (in some sort of 'any' or 'and' sense) within a mutually exclusive group. It's 'xor' for all arguments. ---------- nosy: +paul.j3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24736> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
