From gpiozero import LED
From time import sleep
Led=LED(17)
While True:
	Led.on()
	Sleep(1)
	Led.off
	Sleep(1)
Standard program:
import RPi.GPIO as GPIO
from time import sleep
 GPIO.setwarnings(False)
GPIO.setmode(GPIO.BCM)
 
led_pin = 17
Blink_count=3
Count=0
While(Count<Blink_count):
	GPIO.output(led_pin,true)
	Print(“led on!!”)
	Sleep(3)
	Count+=1
	GPIO.output(led_pin,false)
	Print(“led off!!”)
	Sleep(1)
	Count+=1
Finally:  GPIO.cleanup()
