怎样使用python制作智能五子棋简易版

今天就跟大家聊聊有关怎样使用python制作智能五子棋简易版，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。

前段时间不是制作了一款升级版本五子棋的嘛！

但是居然有粉丝私信我说：

"准备拿到代码玩一下ok过去了！太难了准备放收藏夹"

所噶，今天先放一个简易版本的五子棋给大家看看！学习嘛~从简单到难 还是慢慢来撒~

学玩这篇可以学下一篇难一点的撒：

Pygame实战：下五子棋吗？信不信我让你几步你也赢不了？

正文

嘿嘿！这五子棋只有人机对战了哈！不要看人机对战感觉很简单，其实代码量也超多滴。

主要代码：都有注释的撒！就不一步一步介绍了。
