长是长了点，有些是废话。。。。

'''有个问题请教各位高手，现在在Windows下执行以上两段程序时（直接双击），除了出现
Pmw的窗口界面外，还会出现一个DOS窗口，不知怎么去掉这个DOS窗口？？谢谢！'''

* 把文件的后缀改为.pyw，然后双击就不会出现dos窗口了。 -- [[limodou]]


==== 实例2(24点算法) ====

试着写了一个24点的程序，遍历所有的解法，最多是24×64×5＝7680种可能。有点丑陋而且重解很多，不过还是发上来让大家扔一下。。。python真的是很强大啊～～

==== 实例3(24点游戏) ====

把24点的程序变成了游戏，适合学龄儿童和老年人玩，开发智力，保持思考。 :)

不过还是有bug，如不能接受小键盘输入。。。

如果大家发现bug，请写在下面，或者和我联系，谢谢～～

如果不喜欢那些图片，直接删掉就可以～图片是从网上当的，如果侵犯了谁的权利，请告知，我立刻撤了～
