请用python写一个贪吃蛇游戏

好的，我可以为您编写一个贪吃蛇游戏。以下是一份简单的Python代码示例，可能需要您对其进行调整以适应您的环境和需要：

import pygame
import random

# 定义颜色
white = (255, 255, 255)
black = (0, 0, 0)
red = (213, 50, 80)
green = (0, 255, 0)
blue = (50, 153, 213)

# 设置屏幕大小
dis_width = 800
dis_height = 600

pygame.init()
# 初始化游戏
dis = pygame.display.set_mode((dis_width, dis_height))
pygame.display.set_caption('Snake Game')

clock = pygame.time.Clock()

# 设置字体样式
font_style = pygame.font.SysFont(None, 50)


# 在屏幕上显示消息
def message(msg, color):
    mesg = font_style.render(msg, True, color)
    dis.blit(mesg, [dis_width/6, dis_height/3])


# 游戏主循环
def gameLoop():
    game_over = False
    game_close = False

    # 蛇头的位置和大小
    x1 = dis_width / 2
    y1 = dis_height / 2
    snake_block = 10
    # 蛇的初始长度
    snake_List = []
    Length_of_snake = 1

    # 初始化果实位置
    foodx = round(random.randrange(0, dis_width - snake_block) / 10.0) * 10.0
    foody = round(random.randrange(0, dis_height - snake_block) / 10.0) * 10.0

    # 蛇的移动速度
    x1_change = 0
    y1_change = 0
    snake_speed = 30

    while not game_over:

        while game_close == True:
            # 显示游戏结束提示信息
            dis.fill(blue)
            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:
                        # 退出游戏
                        game_over = True
                        game_close = False
                    if event.key == pygame.K_c:
                        # 重新开始游戏
                        gameLoop()

        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:
                    x1_change = -snake_block
                    y1_change = 0
                elif event.key == pygame.K_RIGHT:
                    x1_change = snake_block
                    y1_change = 0
                elif event.key == pygame.K_UP:
                    y1_change = -snake_block
                    x1_change = 0
                elif event.key == pygame.K_DOWN:
                    y1_change = snake_block
                    x1_change = 0

        # 蛇头的位置发生变化
        x1 += x1_change
        y1 += y1_change

        # 判断是否吃到果实
        if x1 == foodx and y1 == foody:
            foodx = round(random.randrange(0, dis_width - snake_block) / 10.0) * 10.0
            foody = round(random.randrange(0, dis_height - snake_block) / 10.0) * 10.0
            Length_of_snake += 1

        dis.fill(blue)

        # 在屏幕上显示果实
        pygame.draw.rect(dis, green, [foodx, foody, snake_block, snake_block])

        # 更新蛇的位置
        snake_Head = []
        snake_Head.append(x1)
        snake_Head.append(y1)
        snake_List.append(snake_Head)
        if len(snake_List) > Length_of_snake:
            del snake_List[0]

        # 检测是否发生碰撞
        for x in snake_List[:-1]:
            if x == snake_Head:
                game_close = True

        # 在屏幕上显示蛇
        for x in snake_List:
            pygame.draw.rect(dis, black, [x[0], x[1], snake_block, snake_block])

        pygame.display.update()

        # 不断更新屏幕的内容
        if x1 >= dis_width or x1 < 0 or y1 >= dis_height or y1 < 0:
            game_close = True

        # 调整速度
        clock.tick(snake_speed)

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


# 运行游戏
gameLoop()

希望以上代码能够帮助您编写出一个简单的贪吃蛇游戏。
