1.2. 能力自述
刚刚开始学Python，希望聆听和参与大家的讨论
1.2.1. 技术
1.2.1.1. 实例1
新写了一个基于C/S的聊天工具，用了Threading,Pmw,socket 等
Server ：

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
1.2.1.2. 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～～

1.2.1.3. 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～
