使用python完成贪吃蛇游戏

好的，让我们开始吧！首先，我们需要安装Pygame库，它是一个非常流行的Python游戏开发库。

在命令行中输入以下命令安装Pygame：

pip install pygame

安装完成后，我们可以开始编写贪吃蛇游戏了。下面是完整的代码：

import pygame
import random

# 初始化pygame
pygame.init()

# 游戏界面宽度和高度
width = 640
height = 480

# 创建游戏窗口
window = pygame.display.set_mode((width, height))

# 设置游戏标题
pygame.display.set_caption("贪吃蛇游戏")

# 贪吃蛇的颜色
snake_color = (0, 255, 0)

# 食物的颜色
food_color = (255, 0, 0)

# 贪吃蛇坐标和长度
snake = [(200, 200), (210, 200), (220, 200), (230, 200)]
snake_length = len(snake)

# 贪吃蛇移动的方向
direction = "right"

# 随机生成食物的位置
food_pos = (random.randint(0, width-10)//10*10, random.randint(0, height-10)//10*10)

# 得分
score = 0

# 加载字体
font = pygame.font.SysFont("Arial", 20)

# 游戏循环
while True:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            # 关闭游戏
            pygame.quit()
            exit()
        elif event.type == pygame.KEYDOWN:
            # 处理按键事件
            if event.key == pygame.K_UP and direction != "down":
                direction = "up"
            elif event.key == pygame.K_DOWN and direction != "up":
                direction = "down"
            elif event.key == pygame.K_LEFT and direction != "right":
                direction = "left"
            elif event.key == pygame.K_RIGHT and direction != "left":
                direction = "right"

    # 移动贪吃蛇
    if direction == "up":
        snake.pop()
        snake.insert(0, (snake[0][0], snake[0][1]-10))
    elif direction == "down":
        snake.pop()
        snake.insert(0, (snake[0][0], snake[0][1]+10))
    elif direction == "left":
        snake.pop()
        snake.insert(0, (snake[0][0]-10, snake[0][1]))
    elif direction == "right":
        snake.pop()
        snake.insert(0, (snake[0][0]+10, snake[0][1]))

    # 判断贪吃蛇是否吃到了食物
    if snake[0] == food_pos:
        # 重新生成食物的位置
        food_pos = (random.randint(0, width-10)//10*10, random.randint(0, height-10)//10*10)
        # 增加贪吃蛇的长度
        snake.append(snake[-1])
        # 得分加1
        score += 1

    # 检测贪吃蛇是否撞到墙壁或自己
    if snake[0][0] < 0 or snake[0][0] > width-10 or snake[0][1] < 0 or snake[0][1] > height-10:
        # 游戏结束
        print("Game Over!")
        pygame.quit()
        exit()
    for i in range(1, len(snake)):
        if snake[0] == snake[i]:
            # 游戏结束
            print("Game Over!")
            pygame.quit()
            exit()

    # 渲染游戏界面
    window.fill((255, 255, 255))
    for pos in snake:
        pygame.draw.rect(window, snake_color, pygame.Rect(pos[0], pos[1], 10, 10))
    pygame.draw.rect(window, food_color, pygame.Rect(food_pos[0], food_pos[1], 10, 10))
    # 显示得分
    text_surface = font.render("Score: "+str(score), True, (0, 0, 0))
    window.blit(text_surface, (10, 10))
    pygame.display.update()

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

运行代码，就可以开始玩贪吃蛇游戏了！
