Hi, I'm new to python, so please bare with me :)

I was wondering if there's any built-in way in python to append variables to URL's regardless of it's structure.

I would like to have a URL variable (test=1) added to an URL which could have any of the following structures

http://www.aaa.com (would simply add "/?test=1") to the end

http://www.aaa.com/home (like the one above, would simply add "/?test=1") to the end

http://www.aaa.com/?location=home (would figure out there's already a ? being used, and would add &test=1 to the end)

http://www.aaa.com/?location=home&page=1 (like the one above, would figure out there's already a ? being used, and would add &test=1 to the end)

I'd be happy to write domething to do it myself, but if python can already do it somehow, I'd me more than happy to use any built-in functionality that would save me some time ;-)

Thanks in advance
