Modify Power Button Behaviour to 'Hold for three seconds'??

[Chillimonster]

Im using the following shutdown script, but its susceptible to false triggers (Or shutdown if you catch the button etc)

Is there a way to make it wait until the button has been pressed for a period of time (Say three seconds)

I'm running Retropi 4.4 on a Pi3B+

**#!/bin/python

import RPi.GPIO as GPIO
import time
import os

#gpio_pin_number=YOUR_CHOSEN_GPIO_NUMBER_HERE
#Replace YOUR_CHOSEN_GPIO_NUMBER_HERE with the GPIO pin number you wish to use
#Make sure you know which rapsberry pi revision you are using first
#The line should look something like this e.g. "gpio_pin_number=7"

GPIO.setmode(GPIO.BCM)

GPIO.setup(3, GPIO.IN, pull_up_down = GPIO.PUD_UP)

def Shutdown(channel):
	os.system("sudo systemctl poweroff")
	
GPIO.add_event_detect(3, GPIO.FALLING, callback = Shutdown, bouncetime = 2000)
while 1:
	time.sleep(5)
	
GPIO.cleanup()
#Revert all GPIO pins to their normal states (i.e. input = safe)**

You can increase the bouncetime from 2sec to something larger.

Even as it is now, just a single quick push will shut the software down - i dont have to hold the button at all.

Perhaps I need to use a different script that relies on the button being held.
