Yes, it's guaranteed by POSIX/ANSI (see man exit). I was refering to the fact that the automatic flushing of files upon exit is a mere side effect of the implementation based atop stdio stream in cpython 2. It's no guaranteed by any Python spec (and I can't really think of any platform other than C that makes such guarantee). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17852> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
