在之前的文章中已经完成了所有的基础工作，剩下的就是把空填上就可以了。

六、

完成程序

理解一下这个过程：人下了一个子，赋值给me，然后添加到：white_chesses，white_positions，chesses中，改变chess_map相应坐标上的值为1，is_player设置为False，表示人不能再下棋了，当white_chesses的个数是5个以上时，调用checkwin判断是否连5。

如果还要继续，则下棋权力在电脑，调用computerdecision函数算出最有利的步骤，电脑下黑棋，赋值给robot，然后添加到：black_chesses，black_positions，chesses中，改变chess_map相应坐标上的值为2，is_player设置为True，表示下一步由人下棋了，当black_chesses的个数是5个以上时，调用checkwin判断是否连5。

到此为止，实现python+pygame五子棋人机对战。后续会使用套接字socket实现联网对战。
