There was a bug/issue that addressed problems with nested mutually_exclusive_groups. It should be easy to find. The problem is that the usage formatter is brittle, building a string and then striping out "unnecessary" characters. I assume the fix handled the default case (not required), but apparently it missed this variation. I wasn't too involved with that, since in my opinion nesting these groups is useless, and should be avoided. You might as well use one union group. Test the parsing for yourself. ---------- nosy: +paul.j3 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45690> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
