python3批量下图

又发现一个图集,用python3抓下:

import urllib.request def main(): url='http://cdn.test.com/downloads/character' path='/home/me/Pictures/paper/paper-' for i in range(1,400): ii='' if i<10: ii="00"+str(i) elif i<100: ii="0"+str(i) else: ii=str(i) url=url+ii+".jpg" print (url) h='' try: doc=urllib.request.urlopen(url) h=str(doc.info()) except urllib.error.HTTPError: print(ii+'is not exist') if('jpeg' in h): path=path+ii+".jpg" data = urllib.request.urlopen(url).read() f = open(path,"wb") f.write(data) f.close() path='/home/me/Pictures/paper/paper-' print (str(ii)+"OK") url='http://cdn.test.com/downloads/character' if __name__ == "__main__": main()[/code]

有两点改变,python2 import的是urllib,这里用到urlopen,需要import urllib.request。还有就file已经不用了,换成open就好了。getheader函数也没有了。可以对比下python2版本的另一篇python批量下图
