人機(jī)對(duì)戰(zhàn)井字棋游戲

人機(jī)對(duì)戰(zhàn)井字棋游戲，這是由Python語(yǔ)言編寫(xiě)的一款井字棋游戲，下面給出了詳細(xì)的代碼說(shuō)明，感興趣的朋友們可以下載參考。人機(jī)對(duì)戰(zhàn)井字棋游戲直接在Python語(yǔ)言編輯器生成即可獲得游戲本體，可以嘗試與AI進(jìn)行互動(dòng)。

人機(jī)對(duì)戰(zhàn)井字棋游戲代碼說(shuō)明

用pygame實(shí)現(xiàn)交互，程序比較簡(jiǎn)陋，有不足之處歡迎大家批評(píng)指正

AI的移動(dòng)思想

逐個(gè)遍歷每個(gè)空的格子，

如果某個(gè)格子落子后AI能贏就下,

如果對(duì)方能贏AI就堵住。
