使用Python编写包含有import pygame的简洁贪吃蛇代码，并显示运行结果

好的，以下是一个简洁的贪吃蛇游戏代码：

import pygame
import random

# 初始化Pygame
pygame.init()

# 游戏窗口尺寸
window_width = 640
window_height = 480

# 初始化游戏窗口
game_window = pygame.display.set_mode((window_width, window_height))

# 设置游戏标题
pygame.display.set_caption('简洁贪吃蛇')

# 定义颜色
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)

# 定义蛇的初始位置和大小
snake_block_size = 10
snake_list = []
snake_length = 1
snake_pos_x = window_width / 2
snake_pos_y = window_height / 2

# 定义食物初始位置和大小
food_block_size = 10
food_pos_x = round(random.randrange(0, window_width - food_block_size) / 10.0) * 10.0
food_pos_y = round(random.randrange(0, window_height - food_block_size) / 10.0) * 10.0

# 定义蛇的移动速度
snake_speed = 15

# 定义游戏结束的函数
def game_over():
    font_style = pygame.font.SysFont(None, 50)
    message = font_style.render('游戏结束！', True, red)
    game_window.blit(message, [window_width / 3, window_height / 3])
    pygame.display.update()
    pygame.time.delay(2000)

# 游戏循环
game_running = True
while game_running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_running = False

    # 处理按键事件
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        snake_pos_x -= snake_block_size
    elif keys[pygame.K_RIGHT]:
        snake_pos_x += snake_block_size
    elif keys[pygame.K_UP]:
        snake_pos_y -= snake_block_size
    elif keys[pygame.K_DOWN]:
        snake_pos_y += snake_block_size

    # 判断蛇是否吃到食物
    if snake_pos_x == food_pos_x and snake_pos_y == food_pos_y:
        food_pos_x = round(random.randrange(0, window_width - food_block_size) / 10.0) * 10.0
        food_pos_y = round(random.randrange(0, window_height - food_block_size) / 10.0) * 10.0
        snake_length += 1

    # 更新蛇的位置
    snake_head = []
    snake_head.append(snake_pos_x)
    snake_head.append(snake_pos_y)
    snake_list.append(snake_head)
    if len(snake_list) > snake_length:
        del snake_list[0]

    # 判断蛇是否碰到边界或自己
    for block in snake_list[:-1]:
        if block == snake_head:
            game_over()
            game_running = False
    if snake_pos_x < 0 or snake_pos_x >= window_width or snake_pos_y < 0 or snake_pos_y >= window_height:
        game_over()
        game_running = False

    # 绘制游戏界面
    game_window.fill(white)
    pygame.draw.rect(game_window, black, [snake_pos_x, snake_pos_y, snake_block_size, snake_block_size])
    for block in snake_list[:-1]:
        pygame.draw.rect(game_window, black, [block[0], block[1], snake_block_size, snake_block_size])
    pygame.draw.rect(game_window, red, [food_pos_x, food_pos_y, food_block_size, food_block_size])
    pygame.display.update()

    # 控制游戏速度
    clock = pygame.time.Clock()
    clock.tick(snake_speed)

# 退出Pygame
pygame.quit()

你可以将上述代码保存为一个.py文件，然后运行即可看到简洁贪吃蛇游戏的运行结果。
