python - Downloading a list of files from a website -

i have specific requirement need download more 100 files website. wanted download these files file names not consecutive (e.g., www.blah.com/1 , www.blah.com/3, www.blah.com/4, www.blah.com/10). wanted go through sequence , skip if link unavailable. efficient way in python ?

assuming have normal tcp/ip connection follwoing code maybe of use

import urllib2  def download(link, filename):   try:     req=urllib2.urlopen(link)   except urllib2.httperror:     pass   if req.has_data():     open(filename,"wb").write(req.get_data())  #here goes function loops on uri="http://example.com/" x in xrange(1, 101):   download(uri+str(x), str(x))
