paul j3 added the comment: On further thought, I think
group2 = group1.add_mutually_exclusive_group() should have raised an error, stating that a group (argument or mutually exclusive) cannot be added to a mutually exclusive group. Also an argument group should not be added to another argument group. However, adding a mutually exclusive group to an argument group is ok, though only for the undocumented (though tested) purpose of giving it a title. ---------- versions: +Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22047> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
