熟悉Java的jsoup包的话，对于Python的BeautifulSoup库应该很容易上手。

复制代码 代码如下:

coding: utf-8

import sys
import urllib
import urllib2
from BeautifulSoup import BeautifulSoup

question_word = "吃货 程序员"
url = "http://www.baidu.com/s?wd=" + urllib.quote(question_word.decode(sys.stdin.encoding).encode('gbk'))
htmlpage = urllib2.urlopen(url).read()
soup = BeautifulSoup(htmlpage)
print len(soup.findAll("table", {"class": "result"}))
for result_table in soup.findAll("table", {"class": "result"}):
a_click = result_table.find("a")
print "-----标题----\n" + a_click.renderContents()#标题
print "----链接----\n" + str(a_click.get("href"))#链接
print "----描述----\n" + result_table.find("div", {"class": "c-abstract"}).renderContents()#描述
print
