用python搜索google

如果直接用urllib.urlopen(url)会返回一个forbidden的，其实加一个add_header就可以了.
给出一个关键字
word 就会返回搜索结果了。
import urllib
import urllib2
def search(word):
url=r'http://www.google.cn/search?hl=zh-CN&newwindow=1&q='+word+"&start=10&sa=N"
req=urllib2.Request(url)
req.add_header("User-Agent",'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2; .NET CLR 1.1.4322)')
opener=urllib2.build_opener()
text=opener.open(req).read()
return text
python通过socket查询whois脚本

import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(("whois.networksolutions.com", 43))
s.send("sina.com.cn \r\n")
while 1:
v = s.recv(1024)
if v == "" or v == None:
break
print v
s.close()
