# -*- coding: utf-8 -*-

import urllib2from city import citycityname = raw_input('你想查哪个城市的天气？\n')citycode = city.get(cityname)if citycode:    url = 'http://www.weather.com.cn/data/cityinfo/%s.html' % citycode    content = urllib2.urlopen(url).read()print content

urllib2
用来发送网络请求，获取数据

json
用来解析获得的数据

import urllib2web = urllib2.urlopen('http://www.baidu.com')content = web.read()print content

b = open("content.html","w")

b.write(content)

b.close()

# -*- coding: utf-8 -*-import urllib2import jsonfrom city import citycityname = raw_input('你想查哪个城市的天气？\n')citycode = city.get(cityname)if citycode:    url = 'http://www.weather.com.cn/data/cityinfo/%s.html' % citycode    content = urllib2.urlopen(url).read()    data = json.loads(content)    result = data['weatherinfo']    str_temp = ('%s\n%s ~ %s') % (        result['weather'],        result['temp1'],        result['temp2']        )    print str_tempelse:    print '没有找到该城市'

对urllib2和json的用法还不是完全理解，有谁愿意给我讲讲不胜感激～
