Python简单抓取新浪某网页新闻链接及标题

进行了一些拓展（还可以再扩展，吧tele中间路径从主页中获取到，然后用map给用户选择）：

#这里可以再改进，进行扩展，自行输入时间（貌似都一样，正则还是可以用）
#doc = urlopen("http://roll.tech.sina.com.cn/tele/2012-05-01.shtml").read()
newsYear = raw_input("Please input the year likes 2012: ")
newsMouth = raw_input("Please input the mouth likes 03: ")
newsDay = raw_input("Please input the day likes 02: ")
doc = urlopen("http://roll.tech.sina.com.cn/tele/" + \
newsYear + "-" + \
newsMouth + "-" + \
newsDay + \
".shtml").read()

没怎么接触网页及网络相关知识，再用没上手的Python，下面这段程序一波三折，bugs不少，但勉强还算是实现了对http://roll.tech.sina.com.cn/tele/2012-05-01.shtml网页新闻的抓取。win系统服务没加上，及一堆问题，待续……
