Its a terminal I/O function - not a platform function. E.g. On Win only in a rough console msvcrt.kbhit() does it. In PythonWin, IPython, Crust ... things are of course different. On regular Unix terminals you have the sys.stdin file: sys.stdin.read(1) #maybe in a thread and interthread-pass it to your main loop or possibly trick with fcntl.fcntl(sys.stdin, fcntl.F_SETFL, os.O_NDELAY|os.O_NONBLOCK) when nothing is on sys.stdin - you get immediately an IOError: >>> sys.stdin.read(1) Traceback (most recent call last): File "<stdin>", line 1, in ? IOError: [Errno 11] Resource temporarily unavailable And see also other ioctl, termios, tty, cbreak, curses .. functions to get things early before \n buffering depending on the terminal mode ) Robert -- http://mail.python.org/mailman/listinfo/python-list
