Python 2.7 compat

I can confirm this script chokes on Python 2.7; at least because of the use of urllib.request. Using six could alleviate this

I wrote this for 3.4; I can try to add 2.7 compatibility, though - I haven't thought about that at all up to this point.

Yep. You expressed doubt in the article about it; I just thought I'd follow up :)
