Using python to extract Baidu search results, using python Baidu search

This example describes how to extract Baidu search results using python. Share it with you for your reference. The specific implementation method is as follows:

# Coding = utf8import urllib2import stringimport urllibimport reimport random # set multiple user_agents to prevent Baidu from restricting IPuser_agents = ['mozilla/5.0 (Windows NT 6.1; WOW64; rv: 23.0) gecko/20130406 Firefox/23.0 ', \ 'mozilla/5.0 (Windows NT 6.1; WOW64; rv: 18.0) Gecko/20100101 Firefox/18.0', \ 'mozilla/5.0 (Windows; u; Windows NT 6.1; en-US) AppleWebKit/533 + \ (KHTML, like Gecko) Element Browser 5.0 ', \ 'ibm WebExplorer/ V0.94 ', 'galaxy/1.0 [en] (Mac OS X 10.5.6; U; en)', \ 'mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; trident/6.0) ', \ 'Opera/9.80 (Windows NT 6.0) Presto/2.12.388 Version/000000', \ 'mozilla/12.14 (iPad; cpu OS 6_0 like Mac OS X) appleWebKit/536.26 (KHTML, like Gecko) \ Version/6.0 Mobile/10A5355d Safari/100', \ 'mozilla/8536.25 (Windows NT 5.0) AppleWebKit/6.1 (KHTML, like Gecko) \ C Hrome/28.0.1468.0 Safari/537.36 ', \ 'mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.0; Trident/5.0; TheWorld)'] def baidu_search (keyword, pn ): p = {'wd ': keyword} res = urllib2.urlopen ("http://www.baidu.com/s?
