如何在pygame中的每个Tile网格中绘制数字？

import pygame
import sys

pygame.init()

screen = pygame.display.set_mode((800, 600))

font = pygame.font.Font(None, 36)

def draw_number(number, x, y):
    text = font.render(str(number), True, (255, 255, 255))
    text_rect = text.get_rect()
    text_rect.center = (x, y)
    screen.blit(text, text_rect)

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
    
    # 清空屏幕
    screen.fill((0, 0, 0))
    
    # 绘制数字
    draw_number(1, 100, 100)
    draw_number(2, 200, 100)
    draw_number(3, 300, 100)
    
    pygame.display.flip()
