帮我用Python重新写一个更好的贪吃蛇游戏代码

好的，我可以回答这个问题。以下是一个简单的贪吃蛇游戏的Python代码：

import pygame
import random

# 初始化pygame
pygame.init()

# 设置游戏窗口大小
window_width = 500
window_height = 500
window = pygame.display.set_mode((window_width, window_height))

# 设置游戏标题
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)
green = (0, 255, 0)

# 定义蛇的初始位置和大小
snake_block_size = 10
snake_speed = 15
snake_list = []
snake_length = 1

# 定义食物的初始位置和大小
food_block_size = 10
food_x = round(random.randrange(0, window_width - food_block_size) / 10.0) * 10.0
food_y = round(random.randrange(0, window_height - food_block_size) / 10.0) * 10.0

# 定义字体
font_style = pygame.font.SysFont(None, 30)

# 定义函数，用于显示分数
def show_score(score):
    score_text = font_style.render("分数：" + str(score), True, black)
    window.blit(score_text, [0, 0])

# 定义函数，用于画蛇
def draw_snake(snake_block_size, snake_list):
    for x in snake_list:
        pygame.draw.rect(window, green, [x[0], x[1], snake_block_size, snake_block_size])

# 定义函数，用于显示消息
def message(msg, color):
    message_text = font_style.render(msg, True, color)
    window.blit(message_text, [window_width / 6, window_height / 3])

# 游戏循环
game_over = False
while not game_over:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over = True

    # 处理按键事件
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        x_change = -snake_block_size
        y_change = 0
    elif keys[pygame.K_RIGHT]:
        x_change = snake_block_size
        y_change = 0
    elif keys[pygame.K_UP]:
        x_change = 0
        y_change = -snake_block_size
    elif keys[pygame.K_DOWN]:
        x_change = 0
        y_change = snake_block_size
    else:
        x_change = 0
        y_change = 0

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

    # 处理碰撞事件
    for x in snake_list[:-1]:
        if x == snake_head:
            game_over = True
    if food_x < 0 or food_x >= window_width or food_y < 0 or food_y >= window_height:
        game_over = True
    if game_over:
        message("游戏结束，按Q退出，按C重新开始", red)
        pygame.display.update()
        while True:
            for event in pygame.event.get():
                if event.type == pygame.KEYDOWN:
                    if event.key == pygame.K_q:
                        pygame.quit()
                        quit()
                    elif event.key == pygame.K_c:
                        game_over = False
                        snake_list = []
                        snake_length = 1
                        food_x = round(random.randrange(0, window_width - food_block_size) / 10.0) * 10.0
                        food_y = round(random.randrange(0, window_height - food_block_size) / 10.0) * 10.0
                        break

    # 更新食物的位置
    if food_x == snake_head[0] and food_y == snake_head[1]:
        food_x = round(random.randrange(0, window_width - food_block_size) / 10.0) * 10.0
        food_y = round(random.randrange(0, window_height - food_block_size) / 10.0) * 10.0
        snake_length += 1

    # 清空窗口
    window.fill(white)

    # 画蛇和食物
    draw_snake(snake_block_size, snake_list)
    pygame.draw.rect(window, red, [food_x, food_y, food_block_size, food_block_size])

    # 显示分数
    show_score(snake_length - 1)

    # 更新窗口
    pygame.display.update()

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

# 退出pygame
pygame.quit()
quit()

这个代码实现了一个简单的贪吃蛇游戏，包括蛇的移动、食物的生成、碰撞检测、分数统计等功能。你可以根据自己的需求对代码进行修改和优化。
