本程序使用了Python自帶的HTMLParser，從Yahoo Finance指定頁面抓取幾個(gè)字段，代碼30行左右，簡(jiǎn)單實(shí)用，居家旅行必備 :) 

代碼是從官方文檔的HTMLParser的示例程序改成的

https://docs.python.org/2/library/htmlparser.html

完整的代碼和介紹在：

https://bitbucket.org/lsz/html-parser 

代碼如下：

import urllibimport sysimport stringfrom HTMLParser import HTMLParserticker_list = ["ibb", "socl", "pnqi", "qqq", "vbk", "eirl", "ewi", "pbd", "ita", "dfe"]ticker = ticker_list[0]class MyHTMLParser(HTMLParser):	    def handle_data(self, data):    starttag_text = self.get_starttag_text()    ticker_str = "(%s)" % ticker    if -1!=string.find(data, ticker_str.upper()) and -1!=string.find(starttag_text, "<h2>"):      sys.stdout.write(data)          if -1!=string.find(str(starttag_text), "yfs_g53_%s" % ticker.lower()) and -1==string.find(data, "-"):      sys.stdout.write("\t")      sys.stdout.write(data)          if -1!=string.find(str(starttag_text), "yfs_h53_%s" % ticker.lower()):      print "\t", datafor t in ticker_list:  ticker = t  parser = MyHTMLParser()  f = urllib.urlopen("http://finance.yahoo.com/q?s=%s" % ticker)  html_string = f.read()  parser.feed(html_string)
