In most cases we want full buffering when standard I/O is a pipe or disk file. It's more efficient to read/write large chunks from/to the OS. In another message I saw -u mentioned to disable buffering. But that's not sufficient. We need -i to force running the built-in REPL over a pipe, and optionally -q to quiet the initial banner message. _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
