简单的一个例子，是以前用Dephi写的，前不久刚实现了一个在Python中使用Delphi控件来编写界面程序，于是趁热写一个类似的的查询方案。
本实例是通过www.ip138.com这个网站来查询的，这里需要的几个知识点，就是用Python模拟网页提交数据，获得数据返回信息，以及对返回的Html信息进行解析，模拟Http提交,Python自带有一个urllib和urllib2这两个库，相当方便，只是奇怪，为什么不将两个库合并成一个，这样来的更方便。然后就是窗体了，窗体还是用我之前写的一个Python模块DxVcl，就是可以在Python中调用Delphi界面控件的一个模块库。下面就贴上代码，相当简单的！
