Making Raspberry Pi Traffic Light.
This is a good example of how to switch on/off a GPIO

import RPi.GPIO as GPIO
import time

try:
  while True:
    GPIO.setwarnings(False)
    GPIO.setmode(GPIO.BOARD)
    
    GPIO.setup(8, GPIO.OUT)
    GPIO.setup(10, GPIO.OUT)
    GPIO.setup(12, GPIO.OUT)
    
    GPIO.output(8, GPIO.LOW)
    GPIO.output(10, GPIO.LOW)
    GPIO.output(12, GPIO.HIGH)
    time.sleep(5)
    
    GPIO.output(8, GPIO.LOW)
    GPIO.output(10, GPIO.HIGH)
    GPIO.output(12, GPIO.LOW)
    time.sleep(1)
    
    GPIO.output(8, GPIO.HIGH)
    GPIO.output(10, GPIO.LOW)
    GPIO.output(12, GPIO.LOW)
    time.sleep(5)
    
except KeyboardInterrupt:
  p.stop()
  GPIO.cleanup()
