My code is supposed to check my mouse position then print it but it only checks it once, whats the issue? 

```
import pygame, sys, time 
from pygame.locals import *

pygame.init()
WINDOW_WIDTH = 1000
WINDOW_HEIGHT = 600
surface = pygame.display.set_mode ((WINDOW_WIDTH, WINDOW_HEIGHT),0,32)
pygame.display.set_caption ('get POS')

while True:
    amntTuple = pygame.mouse.get_pos()
    print (amntTuple)
    time.sleep(0.2)

```
