> Z/1Z is a perfectly-well-defined ring. More to the point, it's a perfectly well-defined ring in which every element is invertible. That's why the Euler phi function has phi(1) = 1 (rather than phi(1) = 0), for example. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37893> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
