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。
