    At the end any program, it is good practice to clean up any resources you might have used. This is no different with RPi.GPIO.
    By returning all channels you have used back to inputs with no pull up/down, you can avoid accidental damage to your RPi by shorting out the pins.
    Note that this will only clean up GPIO channels that your script has used.
    :param channel: It is possible that you only want to clean up one channel, leaving some set up when your program exits
