[Tutor] Need a bump in the right direction (network programming)

[Cheeyung]

I'm creating a mobile application and I'm using python for a desktop 
server. However, I don't have access to a static IP on the desktop, but 
do have a website. Is it possible to connect from mobile -> http website 
-> desktop server and back?

What kind of (python) libraries/functions am I looking for?

As you can see, I'm completely clueless about where to begin. If someone 
could recommend a resource to learn network programming, that would be 
great too!

Thanks!
