请用python编写一个贪吃蛇小游戏，并给出完整代码

我可以尝试给出一些提示。首先，可以使用Python的pygame模块来创建游戏窗口，并在其中绘制贪吃蛇和食物。然后，使用Python的list数据结构来存储贪吃蛇的每一部分的坐标。然后，您可以使用random模块来在随机位置绘制新的食物。最后，可以使用if-else语句来实现贪吃蛇移动和吃掉食物的逻辑。

帮我用Python编写一个贪吃蛇小游戏

非常感谢您的提问。我可以回答这个问题。以下是一个简单的 Python 贪吃蛇小游戏的代码示例：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 游戏窗口的大小
window_width = 500
window_height = 500

# 创建游戏窗口
game_window = pygame.display.set_mode((window_width, window_height))

# 设置游戏窗口标题
pygame.display.set_caption('贪吃蛇小游戏')

# 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
snake_x = window_width / 2
snake_y = window_height / 2

# 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)

# 定义显示分数的函数
def show_score(score):
    score_text = font_style.render('分数: ' + str(score), True, black)
    game_window.blit(score_text, [0, 0])

# 定义画蛇的函数
def draw_snake(snake_block_size, snake_list):
    for x in snake_list:
        pygame.draw.rect(game_window, green, [x[0], x[1], snake_block_size, snake_block_size])

# 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]:
        snake_x -= snake_block_size
    elif keys[pygame.K_RIGHT]:
        snake_x += snake_block_size
    elif keys[pygame.K_UP]:
        snake_y -= snake_block_size
    elif keys[pygame.K_DOWN]:
        snake_y += snake_block_size

    # 判断是否吃到食物
    if snake_x == food_x and snake_y == food_y:
        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

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

    # 判断是否撞墙或撞到自己
    for x in snake_list[:-1]:
        if x == snake_head:
            game_over = True
    if snake_x < 0 or snake_x >= window_width or snake_y < 0 or snake_y >= window_height:
        game_over = True

    # 清空游戏窗口
    game_window.fill(white)

    # 画食物和蛇
    pygame.draw.rect(game_window, red, [food_x, food_y, food_block_size, food_block_size])
    draw_snake(snake_block_size, snake_list)

    # 显示分数
    show_score(snake_length - 1)

    # 更新游戏窗口
    pygame.display.update()

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

# 退出 Pygame
pygame.quit()
