import concurrent.futures import urllib.request catname = 'amateur' def getimg(count): localpath = '{0}/images/{0}{1}.jpg'.format(catname, count) urllib.request.urlretrieve(urls[count], localpath) urls[count] = localpath concurrent.futures.threadpoolexecutor(max_workers=50) e: in range(5000): e.submit(getimg, i)
