Python实现四个经典小游戏合集
作者：嗨学编程
这篇文章主要介绍了利用Python编写一个经典小游戏的合集，包括：贪吃蛇，扫雷，俄罗斯方块，五子棋。感兴趣的小伙伴可以跟随小编一起学习一下
一、效果展示
1、俄罗斯方块
这个应该是玩起来最最简单的了…
2、扫雷
运气好，点了四下都没踩雷哈哈…
3、五子棋
我是菜鸡，玩不赢电脑人…
4、贪吃蛇
害，这个是最惊心动魄的，为了我的小心脏，不玩了不玩了…
女朋友：你就是借机在玩游戏，逮到了
啊这…
那我不吹牛逼了，我们来敲代码吧~
二、代码展示
1、俄罗斯方块
方块部分
这部分代码单独保存py文件，这里我命名为 blocks.py
方块形状的设计，一开始我是做成 4 × 4，长宽最长都是4的话旋转的时候就不考虑怎么转了，就是从一个图形替换成另一个。
要实现这个功能，只要固定左上角的坐标就可以了。

Point = namedtuple('Point', 'X Y')
Shape = namedtuple('Shape', 'X Y Width Height')

'...'], Point(0, 0), Point(2, 1), 'S', 1),

# T型方块
