python截取搜索引擎关键词

这段代码是自己学了python的基本语法之后，参考一个网上视频写的代码，功能是截取搜索引擎360的关键词。

代码：

 #!/usr/bin/python
 #encoding:utf-8

 import urllib
 import urllib2
 import re
 import time
 from random import choice

 ipList = ['1.9.189.65:3128', '27.24.158.130:80', '27.24.158.154:80']

 listKeyWords = ["集团", "科技"]
 for item in listKeyWords:
     ip = choice(ipList)
     gjc = urllib.quote(item)
     url = "http://sug.so.360.cn/suggest?callback=suggest_so&encodein=utf-8&encodeout=utf-8&word=" + gjc
     headers = {
         "GET":url,
         "Host":"sug.so.360.cn",
         "Referer":"http://www.so.com/",
         "User-Agent":"Mozilla/5.0 (X11; Linux i686) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/37.0.2062.120 Chrome/37.0.2062.120 Safari/537.36"
     }

     #proxy_support = urllib2.ProxyHandler({"http":"http://"+ip})

     #opener = urllib2.build_opener(proxy_support)
     #urllib2.install_opener(opener)
     req = urllib2.Request(url)

     for key in headers:
         req.add_header(key, headers[key])

     html = urllib2.urlopen(req).read()
     print html

     ss = re.findall("\"(.*?)\"", html)
     for item in ss:
         print item

     time.sleep(3)

主要使用了python自i带的几个库，用法可以查看帮助文档。
