Seems kinda useful, but I have two concerns. (1) Perhaps this would be better as a recipe using ExitStack (plus a new redirect_stdin)? https://docs.python.org/3/library/contextlib.html#contextlib.ExitStack (2) I don't see `redirect_stdio(stout=None ...)` as meaning "leave stdout alone". I see it as equivalent to some variation of unsetting stdout, say setting it to /dev/null. I don't know how I would *not* redirect stdout, except to just not redirect it. Overall: Add redirect_stdin: +1 (regardless of what we do with redirect_stdio) Add an ExitStack recipe: +1 Add redirect_stdio: -0 Use None to mean "don't change": -1 Use None to mean "redirect to nowhere": +1 -- Steve _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/GNJX2FKDQY2RI2OPG2IQ74QFIYKBQWS2/ Code of Conduct: http://python.org/psf/codeofconduct/
