        print "Failure -> {:>75}".format(response.url)


if __name__ == '__main__':
    urls = "http://www.google.com http://www.bing.com http://www.yahoo.com http://news.ycombinator.com".split()

    for u in urls:
        Thread(target=download, args=(u,)).start()

This is a simple script that sends a get request to a url (there...
