How to do it...

Create the btntest.py script as follows:

#!/usr/bin/python3 
#btntest.py 
import time 
import os 
import RPi.GPIO as GPIO 
#HARDWARE SETUP 
# GPIO 
# 2[==X==1=======]26[=======]40 
# 1[=============]25[=======]39 
#Button Config 
BTN = 12 
 
def gpio_setup(): 
  #Setup the wiring 
  GPIO.setmode(GPIO.BOARD) 
  #Setup Ports 
  GPIO.setup(BTN,GPIO.IN,pull_up_down=GPIO.PUD_UP) 
   
 
def main(): 
  gpio_setup() 
  count=0 
  btn_closed = True 
  while True: 
    btn_val = GPIO.input(BTN) 
    if btn_val and btn_closed: 
       print("OPEN") 
       btn_closed=False 
    elif btn_val==False and btn_closed==False: 
       count+=1 
       print("CLOSE %s" % count) 
       os.system("flite -t '%s'" % count) 
       btn_closed=True 
    time.sleep(0.1) 
 
 
try: 
  main() 
finally: 
  GPIO.cleanup() 
  print("Closed Everything. END") 
#End
