如何在pygame中创建一个“当鼠标按下”循环

import pygame
import sys

pygame.init()

window_size = (800, 600)
screen = pygame.display.set_mode(window_size)
pygame.display.set_caption("Mouse Click Loop")

running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.MOUSEBUTTONDOWN:
            # 鼠标按下的操作
            pass

elif event.type == pygame.MOUSEBUTTONDOWN:
    mouse_pos = pygame.mouse.get_pos()
    print("鼠标位置：", mouse_pos)

pygame.display.flip()

pygame.quit()
sys.exit()
