How to easily extract ID from iTunes URL using Python

iTunes URLs look like the following:

http://itunes.apple.com/us/album/break-of-dawn/id472335316?ign-mpt=uo%3D
http://itunes.apple.com/us/app/monopoly-here-now-the-world/id299110947?mt=8

How can I easily extract id number?

get_id("http://itunes.apple.com/us/album/brawn/id472335316?ign-mpt=uo")

#returns 472335316
