You want to create a program that blinks two LEDs on pins 17 and 27 alternately every 0.5 seconds for 5 seconds total. Which code snippet correctly implements this using the LED class?

from gpiozero import LED
from time import sleep

led1 = LED(17)
led2 = LED(27)

start = 0
while start < 5:
    led1.on()
    led2.off()
    sleep(0.5)
    led1.off()
    led2.on()
    sleep(0.5)
    start += 1

led1.off()
led2.off()
led1.close()
led2.close()
