I still don't like it. If a function returns a number of CPU, it should either return an integer >= 1, or raise an exception. None is *not* an integer. And returning an exception is IMO useles, since the user can't do anything with anyway, other than fallback to 1. > Just write "os.cpu_count() or 1" if you need 1 when the count is unknown ;-) os.cpu_count() or 1 is an ugly idiom. > See also #17444, Trent Nelson wrote an implementation of os.cpu_count(). I don't see exactly what this C implementation brings over the one in multiprocessing (which is written in Python)? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17914> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
