你和我遇到的问题一样  主要是缩进问题；我现在只能出一条就停止了。

new_urls, new_data = self.parser.parser(new_url, html_cont)

这句代码怎么理解，分别给new_urls,new_data复制么？

from spirder import manager, downloader, parser, output


class spirdermain(object):
    def __init__(self):
        self.manager=manager.UrlManager()
        self.downloader=downloader.HtmlDownloader()
        self.parser=parser.HtmlParser()
        self.output=output.HtmlOutput()
        
    def craw(self, root_url):
        count=1
        self.manager.add_new_url(root_url)
        while self.manager.has_new_url():
            try:
                new_url=self.manager.get_new_url()
                print 'craw %d:%s'%(count,new_url)
                html_cont=self.downloader.downloader(new_url)
                new_urls,new_data=self.parser.parser(new_url,html_cont)
                self.manager.add_new_urls(new_urls)
                self.output.collect_data(new_data)
                if count==1000:
                    break
                count=count+1
            except:
                print 'craw failed'
        self.output.output_html()    

if __name__=="_main_":
    root_url="http://baike.baidu.com/link?url=sP2Dq8raiXUsDeUd8GbiC1C1HcvMO8I8dkoUi5UcIiDwFckEBG9G4KHTKVsCPWoPh1y4LDZZKtEeIA59EYISx_"
    obj_spirder=spirdermain()
    obj_spirder.craw(root_url)

额，这是代码。。。。。英文打错了，打成spirder了，但是应该没问题的
