Serhiy Storchaka <storchaka+cpyt...@gmail.com> added the comment: In Python 2 there is an internal buffering in xreadlines(), readlines() and file-object iterators. You need to enter many lines first that the program get the first of them. And -u doesn't help.
But in Python 3 the program gets the input right as it becomes available. Reading is not blocked if the input is available. There are internal buffers, but they affect only performance, not the behavior. If you can edit a line before pressing Enter, this is because your terminal buffers a line before sending it to the program. I think it is more correct to say that stdin is always unbuffered in Python 3. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue28647> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
