python实例31[My Stock Info]

 

本程序使用python3.1实现的一个运行于Windows的控制台小程序，用来显示你所关心的股票的实时价格。

1）每隔一分钟跟新一次，当然你可以改为更短的时间间隔；

2）控制台彩色显示的python模块为WConio，需要单独下载：http://newcenturycomputers.net/projects/wconio.html

3）webservice来源于sina，感谢sina，例如http://hq.sinajs.cn/list=sh600547， 返回的结果如下：

var hq_str_sh600547="山东黄金,51.02,51.00,52.71,52.86,50.68,52.70,52.72,16389139
,850524809,3000,52.70,52500,52.69,100,52.67,28849,52.66,7400,52.65,1200,52.72,43
77,52.75,11200,52.76,20000,52.77,4000,52.78,2010-12-31,15:02:06";

 

 

4) 也可以使用其他的股票web service （http://www.webxml.com.cn/WebServices/ChinaStockWebService.asmx/getStockInfoByCode?theStockCode=sh600547），返回的结果如下：

数据输入： （stocks.txt 此文件需要跟Mystockinfo.py在统一目录下，你可以自由的增加自己关注的股票代码）

sh601601
sh600547
sz300027
sh600196
sz002299
sh601766

  

运行结果：

 

运行： （MyStockInfo.bat 双击此文件即可运行了，或者还可以对此文件创建桌面快捷方式，再桌面上直接运行）

c:\python31\python.exe mystock.py

  

如果希望在python2.6下运行，则需要

1）在所有的类的静态函数前加上   @staticmethod  ；

2） 修改urllib.request为urllib2；

 

希望大家能够继续改进和共享！

 

完!
