                content=response.read().decode(‘utf-8‘)
                pattern=re.compile(‘<div class="article block untagged.*?<div.*?clearfix">.*?<span>(.*?)</span>‘,re.S)
                items=re.findall(pattern,content)
                text=re.compile(‘<br/>‘)
                for item in items:
                        print re.sub(text,‘\n‘,item)
                        print
                q=raw_input()
                if q == ‘q‘:break
                page=page+1
except urllib2.URLError,e:
        if hasattr(e,‘code‘):
                print e.code
        if hasattr(e,‘reason‘):
                print e.reason

实现的功能比较简单，按回车键会爬下一页的段子，输入q退出
