Python贪吃蛇游戏的示例代码：

pygame.init()

# 定义颜色

# 创建游戏窗口
gameDisplay = pygame.display.set_mode((display_width, display_height))

# 设置游戏时钟
clock = pygame.time.Clock()

# 定义蛇的大小和移动速度

# 定义字体样式和大小

# 显示得分

        snake_Head.append(x1)

        our_snake(snake_block, snake_List)
        your_score(Length_of_snake - 1)

        pygame.display.update()

        # 吃到食物的判断
        if x1 == foodx and y1 == foody:
            foodx = round(random.randrange(0, display_width - snake_block) / 10.0) * 10.0
            foody = round(random.randrange(0, display_height - snake_block) / 10.0) * 10.0
            Length_of_snake += 1

        # 控制帧率
        clock.tick(snake_speed)

    pygame.quit()
    quit()

# 运行游戏
gameLoop()
运行以上代码，即可启动一个贪吃蛇游戏。你可以用方向键控制蛇的移动，吃到食物后蛇的长度会增加，如果蛇撞到边界或者自己，游戏结束。
