Pygame 做的中国象棋，一直以来喜欢下象棋，写了 python 就拿来做一个试试，水平有限，电脑走法水平低，需要在下次版本中更新电脑走法，希望源码能帮助大家更好的学习 python。总共分为四个文件，chinachess.py 为主文件，constants.py 数据常量，pieces.py 棋子类，走法，computer.py 电脑走法计算。

 PS:另外很多人在学习Python的过程中，往往因为遇问题解决不了或者没好的教程从而导致自己放弃，为此我整理啦从基础的python脚本到web开发、爬虫、django、数据挖掘等【PDF等】需要的可以进Python全栈开发交流.裙 ：一久武其而而流一思（数字的谐音）转换下可以找到了，里面有最新Python教程项目可拿,不懂的问题有老司机解决哦，一起相互监督共同进步
