I am a little concerned with MRAB's report that

import sys print("hello") sys.stdout.flush() sys.stdout = open(sys.stdout.fileno(), 'w', encoding='utf-8') print("hello") doesn't work as expected, though.  (It does work for me on Mac OS X, both as above -- of course there are no '\r's in the output -- and with 'print("hello", end="\r\n")'.) That's actually Python 3.1. From Python 3.2 it's slightly different, but still not quite right: Python 3.1:     "hello\r\nhello\r\r\n" Python 3.2:     "hello\nhello\r\n" Python 3.3.0a4: "hello\nhello\r\n" All on Windows.

Not here (Win 7 32-bit):

PS D:\Data> type t.py import sys print("Hello!") sys.stdout.flush()

sys.stdout = open(sys.stdout.fileno(), 'w', encoding='utf-8') print("Hello!") PS D:\Data> py -3.2 t.py | od -c 0000000 H e l l o ! \r \n H e l l o ! \r \n 0000020
