用Tkinter做一个五子棋游戏，但是我在做的时候心血来潮，决定稍微改变一下规则，于是在五子棋的基础上开发出了“四五棋”，具体规则如下：
一方连成四子得一分；
一方连成五子及以上得五分；
当棋盘落满后，比较双方得分，较高的一方获胜。
接下来就是用tkinter来实现它了，具体流程主要分为几部分：
（1）棋盘绘制：15x15；
（2）落子的相应判断：先判断点击的位置是否是棋盘线交叉点，然后判断是黑方还是白方，若落子点上没有棋子，则落子；
（3）得分判断：每次落子后，从当前棋子的横、竖、斜三个方向寻找连子（不包括该棋子本身），找到三个则加一分，找到四个及以上则加五分；
（4）胜负判断：若棋盘落满，根据双方得分判断胜负；
（5）悔棋：删除上一步绘制的棋子，并将其移除棋子列表，减去相应分数；
（6）信息显示：显示当前执子方和得分。
与tkinter相关的部分主要用到了canvas.create_oval绘制棋子，以及Label显示信息，其余大多是各种判断的算法。下面是完整代码：
