Python Download Images With Alernating Variables

I was trying to download images with url's that change but got an error. url_image='http://www.joblo.com/timthumb.php?src=/posters/images/full/'+str(title_2)+'-poster1.jpg&h=33

Solution 1:

My advice is to use urlib2. In addition, I've written a nice function (I think) that will also allow gzip encoding (reduce bandwidth) if the server supports it. I use this for downloading social media files, but should work for anything.

I would try to debug your code, but since it's just a snippet (and the error messages are formatted badly), it's hard to know exactly where your error is occurring (it's certainly not line 97 in your code snippet).

This isn't as short as it could be, but it's clear and reusable. This is python 2.7, it looks like you're using 3 - in which case you google some other questions that address how to use urllib2 in python 3.

import urllib2
import gzip
from StringIO import StringIO

defdownload(url):
    """
    Download and return the file specified in the URL; attempt to use
    gzip encoding if possible.
    """
    request = urllib2.Request(url)
    request.add_header('Accept-Encoding', 'gzip')
    try:
        response = urllib2.urlopen(request)
    except Exception, e:
        raise IOError("%s(%s) %s" % (_ERRORS[1], url, e))
    payload = response.read()
    if response.info().get('Content-Encoding') == 'gzip':
        buf = StringIO(payload)
        f = gzip.GzipFile(fileobj=buf)
        payload = f.read()
    return payload

defsave_media(filename, media):
    file_handle = open(filename, "wb")
    file_handle.write(media)
    file_handle.close()

title_2 = "10-cloverfield-lane"
media = download("http://www.joblo.com/timthumb.php?src=/posters/images/full/{}-poster1.jpg&h=333&w=225".format(title_2))
save_media("poster.jpg", media)
