gpio BCM and BOARD mode

1. GPIO.setmode(GPIO.BOARD)
   pin numbers are as in board,1,2...40 sequentially. 
2. GPIO.setmode(GPIO.BCM)
   pin numbers are as defined names as GPIO 14, GPIO 15 ...
3. For example, pin 16 in BOARD mode is the pin GPIO 23 in BCM mode

gpio output vs input

 cf: https://electronics.stackexchange.com/questions/534268/difference-between-low-output-gpio-and-input-gpio

An output pin that is set high can push out (source) current, or when set low it can pull in (sink) current. An input does neither, it ideally needs no current to flow to sense if the input is high or low.
