**正文开始**  
下载pygame模块

pip install pygame

编写的是最简单的贪吃蛇游戏（实现最基本的功能）  
效果图：

附上代码：

    color_white = pygame.Color(255, 255, 255)

    pygame.init()
    screen = pygame.display.set_mode((600, 400))
    screen.fill(color_white)
    pygame.display.set_caption("贪吃蛇小游戏")
    arr = [([0] * 41) for i in range(61)]  # 创建一个二维数组
    x = 10  # 蛇的初始x坐标
    y = 10  # 蛇的初始y坐标
    foodx = random.randint(1, 60)  # 食物随机生成的x坐标
    foody = random.randint(1, 40)  # 食物随机生成的y坐标
    arr[foodx][foody] = -1
    snake_lon = 3  # 蛇的长度
    way = 1  # 蛇的运动方向
