def get_line(prompt=""):
  fd = sys.stdin.fileno()
  old = termios.tcgetattr(fd)
  new = termios.tcgetattr(fd)
  new[3] = new[3] & ~termios.ICANON
  try:
    termios.tcsetattr(fd, termios.TCSADRAIN, new)
    line = input(prompt)
  finally:
    termios.tcsetattr(fd, termios.TCSADRAIN, old)
  return line
  
s = get_line()
