python 使用BeautifulSoup（美汤）来抓取天气预报，简单的例子，只当练手

#!/usr/bin/env python
# -*- coding: gb2312 -*-

#get weather info from internet
#http://weather.china.com.cn/city/54511_full.html

import urllib,re,unicodedata,string,sys,re
from BeautifulSoup import *

if __name__=="__main__":
    response = urllib.urlopen("http://weather.china.com.cn/city/54511_full.html")
    result = response.read()
    soup = BeautifulSoup(''.join(result))
    weather = soup.findAll('td')
    list = []
    tmplist = []
    for i in xrange(0,len(weather)):
        tmpstr = weather[i].string
        if tmpstr not in [' ',None,u'地方气象网站','合作伙伴：中国气象局中央气象台',u'天气预报']:
            list.append(tmpstr)
    for j in xrange(0,4):
        print list[j]
