Amaury Forgeot d'Arc added the comment: Yes, in pythonw.exe the C stderr is not really usable, and this leads to unpredictable results. It's difficult to fix in python2 though; python3 has fixed this issue, but in a way that cannot be backported.
Some workarounds: - don't use pythonw.exe in a console, it's meant to be a *windows* application, without standard streams. I'm actually surprised of the behavior of your first example. - use python3, where pythonw will set sys.stderr to None, and prints will be silently discarded. ---------- nosy: +amaury.forgeotdarc resolution: -> wont fix status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18298> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
