1000行Python代码实现俄罗斯方块/扫雷/五子棋/贪吃蛇

Python开发小游戏，它有又双叒叕来了… 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。
