用Python编写贪吃蛇

很抱歉，作为AI语言模型，我不能在本地运行代码。但是，我可以为您提供Python编写贪吃蛇的示例代码：

import pygame
import random

# 初始化游戏
pygame.init()

# 设置游戏窗口大小和标题
window_width = 600
window_height = 600
window = pygame.display.set_mode((window_width, window_height))
pygame.display.set_caption("Snake Game")

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

# 定义蛇的大小和速度
snake_size = 10
snake_speed = 15

# 定义字体
font = pygame.font.SysFont(None, 25)

# 定义函数：绘制蛇
def draw_snake(snake_size, snake_pixels):
    for pixel in snake_pixels:
        pygame.draw.rect(window, green, [pixel[0], pixel[1], snake_size, snake_size])

# 定义函数：显示消息
def message(msg, color):
    screen_text = font.render(msg, True, color)
    window.blit(screen_text, [window_width/6, window_height/2])

# 定义函数：游戏循环
def game_loop():
    game_over = False
    game_close = False

    x = window_width / 2
    y = window_height / 2

    x_change = 0
    y_change = 0

    snake_pixels = []
    snake_length = 1

    # 随机生成食物的位置
    food_x = round(random.randrange(0, window_width - snake_size) / 10.0) * 10.0
    food_y = round(random.randrange(0, window_height - snake_size) / 10.0) * 10.0

    # 游戏循环
    while not game_over:

        while game_close == True:
            window.fill(white)
            message("You Lost! Press Q-Quit or C-Play Again", red)
            pygame.display.update()

            for event in pygame.event.get():
                if event.type == pygame.KEYDOWN:
                    if event.key == pygame.K_q:
                        game_over = True
                        game_close = False
                    if event.key == pygame.K_c:
                        game_loop()

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                game_over = True
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    x_change = -snake_size
                    y_change = 0
                elif event.key == pygame.K_RIGHT:
                    x_change = snake_size
                    y_change = 0
                elif event.key == pygame.K_UP:
                    y_change = -snake_size
                    x_change = 0
                elif event.key == pygame.K_DOWN:
                    y_change = snake_size
                    x_change = 0

        # 判断蛇是否撞墙
        if x >= window_width or x < 0 or y >= window_height or y < 0:
            game_close = True

        x += x_change
        y += y_change

        window.fill(white)

        # 绘制食物
        pygame.draw.rect(window, red, [food_x, food_y, snake_size, snake_size])

        # 更新蛇的位置
        snake_pixels.append([x, y])
        if len(snake_pixels) > snake_length:
            del snake_pixels[0]

        # 判断蛇是否吃到食物
        for pixel in snake_pixels[:-1]:
            if pixel == [x, y]:
                game_close = True

        # 绘制蛇
        draw_snake(snake_size, snake_pixels)

        # 更新窗口
        pygame.display.update()

        # 判断蛇是否吃到食物
        if x == food_x and y == food_y:
            food_x = round(random.randrange(0, window_width - snake_size) / 10.0) * 10.0
            food_y = round(random.randrange(0, window_height - snake_size) / 10.0) * 10.0
            snake_length += 1

        # 控制蛇的速度
        pygame.time.Clock().tick(snake_speed)

    # 退出游戏
    pygame.quit()
    quit()

game_loop()
