Steve Dower <steve.do...@python.org> added the comment:
This is normal, if obscure, behaviour. Pythonw starts without a console, and so stdout is not connected to anything. As a result, you can't print (or pprint). You'll need to set sys.stdout to something or provide a file if you want to print output. If someone wants to contribute a specialised sys.stdout implementation that can raise a more helpful error message in this case, that would be helpful. But as it's a breaking change it would only go into 3.10. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41546> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
