blinking an led with raspberry pi

import RPi.GPIO as GPIO # IMPORTANT: remember to change the gpio pin (18) also it needs to be programmed in Thonny Python IDE
import time #used in raspberry pi model 4

GPIO.setwarnings(False) #NOTE: raspberry pi could be updated, and you might need to change your code
GPIO.setmode(GPIO.BCM) 
GPIO.setup(18, GPIO.OUT)


while True:
      GPIO.output(18, True) 
      time.sleep(1) 
      GPIO.output(18, False) 
      time.sleep(1)

how to make 2 lights blink with the GPIO pins with python

while True:
    import RPi.GPIO as GPIO
    import time
    
    x = (0.3)
    
    GPIO.setmode(GPIO.BOARD)
    GPIO.setup(3, GPIO.OUT)
    GPIO.setup(5, GPIO.OUT)
    
    GPIO.output(3, GPIO.LOW)
    GPIO.output(5, GPIO.HIGH)
    time.sleep(x)
    GPIO.output(3,GPIO.HIGH)
    GPIO.output(5, GPIO.LOW)
    time.sleep(x)
    
GPIO.cleanup()
