Exceptions: ^z

You'd use signal.signal(signal.SIGTSTP, signal_handler_function)

I wouldn't want to actually do that, myself.  Partly because UNIX signal
handling and Python don't get along too well, partly because it doesn't
pay to tinker with the delicate machinery of Berkeley job control.

If all you really want is to turn off this feature, do that with
the terminal driver:

  import termios
  import TERMIOS

  attr = termios.getattr(0)
  attr[6][TERMIOS.VSUSP] = '\000'   # '\032' sets it back to ^Z
  termios.setattr(0, TERMIOS.TCSANOW, attr)
