代码如下:

    def reset(self):
        sgmlparser.reset(self)
        self.srcs=[]
        self.istrue=true

        for k,v in artts:
            if v==author:
                self.istrue=false
    def end_div(self):
        self.istrue=true
    def start_img(self,artts):
        for k,v in artts:
            if k==src and self.istrue==true:
                self.srcs.append(v)
    def download(self):
        for src in self.srcs:
            f=open(src[-12:],wb)
            print src
            img=urllib2.urlopen(src)
            f.write(img.read())
            f.close()
sgm=sgm()
for page in range(1,500):
    url=http://www.qiushibaike.com/late/page/%s?s=4622726 % page
    data=urllib2.urlopen(url).read()
    sgm.feed(data)
    sgm.download()
