I'm trying to write a program that needs to detect key presses, which I've already done using this code I found online:
TERMIOS = termios def getkey(): fd = sys.stdin.fileno() old = termios.tcgetattr(fd) new = termios.tcgetattr(fd) new = new & ~TERMIOS.ICANON & ~TERMIOS.ECHO new[TERMIOS.VMIN] = 1 new[TERMIOS.VTIME] = 0 termios.tcsetattr(fd, TERMIOS.TCSANOW, new) c = '' try: c = repr(sys.stdin.read(1)) finally: termios.tcsetattr(fd, TERMIOS.TCSAFLUSH, old) return c
But I can't seem to find any good way to make it send back a string ("no keypress" or something like that, for example) if it doesn't detect any key press within a certain time period. Anyone have any ideas? I'm using python 2.7.3 on ubuntu 12.03. Thanks.
