请使用python制作一个贪吃蛇游戏

好的，下面是一个简单的Python贪吃蛇游戏代码：

import pygame
import random

# 初始化pygame
pygame.init()

# 游戏窗口大小和标题
win_width = 800
win_height = 600
win = pygame.display.set_mode((win_width, win_height))
pygame.display.set_caption("贪吃蛇游戏")

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

# 定义贪吃蛇的属性
snake_block_size = 10
snake_speed = 15

# 定义字体
font_style = pygame.font.SysFont(None, 50)

# 定义函数：显示得分
def show_score(score):
    score_font = font_style.render("得分：" + str(score), True, black)
    win.blit(score_font, [0, 0])

# 定义函数：绘制贪吃蛇
def draw_snake(snake_block_size, snake_list):
    for x in snake_list:
        pygame.draw.rect(win, black, [x[0], x[1], snake_block_size, snake_block_size])

# 定义主函数
def main():
    # 初始位置
    x1 = win_width / 2
    y1 = win_height / 2
    x1_change = 0
    y1_change = 0

    # 初始长度
    snake_List = []
    Length_of_snake = 1

    # 随机生成食物位置
    foodx = round(random.randrange(0, win_width - snake_block_size) / 10.0) * 10.0
    foody = round(random.randrange(0, win_height - snake_block_size) / 10.0) * 10.0

    # 游戏循环标志
    game_over = False

    # 得分
    score = 0

    # 游戏循环
    while not game_over:
        # 处理事件
        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_size
                    y1_change = 0
                elif event.key == pygame.K_RIGHT:
                    x1_change = snake_block_size
                    y1_change = 0
                elif event.key == pygame.K_UP:
                    y1_change = -snake_block_size
                    x1_change = 0
                elif event.key == pygame.K_DOWN:
                    y1_change = snake_block_size
                    x1_change = 0

        # 判断是否撞墙
        if x1 >= win_width or x1 < 0 or y1 >= win_height or y1 < 0:
            game_over = True

        # 更新贪吃蛇的位置
        x1 += x1_change
        y1 += y1_change

        # 绘制背景
        win.fill(white)

        # 绘制食物
        pygame.draw.rect(win, red, [foodx, foody, snake_block_size, snake_block_size])

        # 贪吃蛇吃到食物，长度+1
        if x1 == foodx and y1 == foody:
            foodx = round(random.randrange(0, win_width - snake_block_size) / 10.0) * 10.0
            foody = round(random.randrange(0, win_height - snake_block_size) / 10.0) * 10.0
            Length_of_snake += 1
            score += 10

        # 绘制贪吃蛇
        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]
        for x in snake_List[:-1]:
            if x == snake_Head:
                game_over = True
        draw_snake(snake_block_size, snake_List)

        # 显示得分
        show_score(score)

        # 刷新游戏界面
        pygame.display.update()

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

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

# 运行主函数
main()

这是一个简单的贪吃蛇游戏，包括了基本的运动、吃食物、增加长度、死亡等功能。你可以根据自己的需求进行修改和扩展。
