用python语言运行的贪吃蛇游戏

抱歉，作为AI语言模型，我无法提供代码运行功能，但我可以为您提供一个基础的贪吃蛇游戏的Python代码，您可以在本地运行它：

import pygame
import random

# 初始化pygame
pygame.init()

# 定义常量
SCREEN_WIDTH = 600
SCREEN_HEIGHT = 600
BLOCK_SIZE = 20
SNAKE_SIZE = 3
FOOD_COLOR = (255, 0, 0)
SNAKE_COLOR = (0, 255, 0)
BG_COLOR = (0, 0, 0)
UP = 1
RIGHT = 2
DOWN = 3
LEFT = 4

# 定义游戏窗口
screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
pygame.display.set_caption("贪吃蛇")

# 创建一个蛇
snake = []
for i in range(SNAKE_SIZE):
    snake.append((int(SCREEN_WIDTH / 2 / BLOCK_SIZE) * BLOCK_SIZE + i * BLOCK_SIZE, int(SCREEN_HEIGHT / 2 / BLOCK_SIZE) * BLOCK_SIZE))

# 创建食物
food_x = random.randint(0, SCREEN_WIDTH / BLOCK_SIZE - 1) * BLOCK_SIZE
food_y = random.randint(0, SCREEN_HEIGHT / BLOCK_SIZE - 1) * BLOCK_SIZE

# 初始方向向右
direction = RIGHT

# 游戏主循环
while True:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_UP and direction != DOWN:
                direction = UP
            elif event.key == pygame.K_RIGHT and direction != LEFT:
                direction = RIGHT
            elif event.key == pygame.K_DOWN and direction != UP:
                direction = DOWN
            elif event.key == pygame.K_LEFT and direction != RIGHT:
                direction = LEFT

    # 移动蛇
    head_x, head_y = snake[-1]
    if direction == UP:
        new_head = (head_x, head_y - BLOCK_SIZE)
    elif direction == RIGHT:
        new_head = (head_x + BLOCK_SIZE, head_y)
    elif direction == DOWN:
        new_head = (head_x, head_y + BLOCK_SIZE)
    elif direction == LEFT:
        new_head = (head_x - BLOCK_SIZE, head_y)
    if new_head[0] < 0 or new_head[0] >= SCREEN_WIDTH or new_head[1] < 0 or new_head[1] >= SCREEN_HEIGHT or new_head in snake:
        # 如果蛇撞墙或者撞自己，游戏结束
        print("游戏结束")
        pygame.quit()
        exit()
    snake.append(new_head)
    if new_head == (food_x, food_y):
        # 如果吃到食物，重新生成食物
        food_x = random.randint(0, SCREEN_WIDTH / BLOCK_SIZE - 1) * BLOCK_SIZE
        food_y = random.randint(0, SCREEN_HEIGHT / BLOCK_SIZE - 1) * BLOCK_SIZE
    else:
        # 如果没有吃到食物，去掉尾巴
        snake.pop(0)

    # 绘制背景
    screen.fill(BG_COLOR)

    # 绘制蛇
    for i in range(len(snake)):
        pygame.draw.rect(screen, SNAKE_COLOR, (snake[i][0], snake[i][1], BLOCK_SIZE, BLOCK_SIZE))

    # 绘制食物
    pygame.draw.rect(screen, FOOD_COLOR, (food_x, food_y, BLOCK_SIZE, BLOCK_SIZE))

    # 更新屏幕
    pygame.display.update()

    # 控制游戏帧率
    pygame.time.Clock().tick(10)
