用pyzhon做一个贪吃蛇小游戏

非常感谢您的问题。以下是使用Pygame写的简单贪吃蛇游戏的代码:

import pygame
import random
 
# 初始化pygame模块
pygame.init()
 
# 游戏界面的大小
screen_size = (600, 400)
screen = pygame.display.set_mode(screen_size)
 
# 设置游戏标题
pygame.display.set_caption("贪吃蛇小游戏")
 
# 定义颜色
white = (255, 255, 255)  # 蛇的颜色
black = (0, 0, 0)  # 游戏背景色
red = (255, 0, 0)  # 食物颜色
 
# 蛇的初始位置
snake_block_size = 10
snake_block_x = random.randrange(0, screen_size[0] - snake_block_size, snake_block_size) 
snake_block_y = random.randrange(0, screen_size[1] - snake_block_size, snake_block_size)
 
# 食物的位置
food_block_size = snake_block_size
food_block_x = random.randrange(0, screen_size[0] - food_block_size, food_block_size)
food_block_y = random.randrange(0, screen_size[1] - food_block_size, food_block_size)
 
# 蛇的移动速度
snake_speed = 10
 
# 初始化蛇的长度为1，头部朝右侧
snake_list = [[snake_block_x, snake_block_y]]
snake_direction = "right"
 
# 定义绘制蛇和食物的函数
def draw_snake(snake_list):
    for block in snake_list:
        pygame.draw.rect(screen, white, [block[0], block[1], snake_block_size, snake_block_size])
 
def draw_food():
    pygame.draw.rect(screen, red, [food_block_x, food_block_y, food_block_size, food_block_size])
 
# 游戏主循环
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
 
        # 处理键盘事件
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT and snake_direction != "right":
                snake_direction = "left"
            elif event.key == pygame.K_RIGHT and snake_direction != "left":
                snake_direction = "right"
            elif event.key == pygame.K_UP and snake_direction != "down":
                snake_direction = "up"
            elif event.key == pygame.K_DOWN and snake_direction != "up":
                snake_direction = "down"
 
    # 根据移动方向更新蛇的坐标
    if snake_direction == "left":
        snake_block_x -= snake_speed
    elif snake_direction == "right":
        snake_block_x += snake_speed
    elif snake_direction == "up":
        snake_block_y -= snake_speed
    elif snake_direction == "down":
        snake_block_y += snake_speed
 
    # 检查蛇是否与边界相撞
    if (snake_block_x < 0 or snake_block_x > screen_size[0] - snake_block_size 
      or snake_block_y < 0 or snake_block_y > screen_size[1] - snake_block_size):
        game_over = True
 
    # 检查蛇是否与自己相撞
    for block in snake_list[1:]:
        if snake_block_x == block[0] and snake_block_y == block[1]:
            game_over = True
 
    # 检查是否吃到食物
    if snake_block_x == food_block_x and snake_block_y == food_block_y:
        food_block_x = random.randrange(0, screen_size[0] - food_block_size, food_block_size)
        food_block_y = random.randrange(0, screen_size[1] - food_block_size, food_block_size)
        snake_list += [[snake_block_x, snake_block_y]]
 
    # 更新蛇的位置
    snake_list = [[snake_block_x, snake_block_y]] + snake_list[:-1]
 
    # 绘制游戏界面
    screen.fill(black)
    draw_snake(snake_list)
    draw_food()
    pygame.display.update()
 
    # 游戏帧数
    clock = pygame.time.Clock()
    clock.tick(20)
 
# 退出pygame模块
pygame.quit()
