Newbie: Python 3 and web applications?

[Rui Maciel]

I'm currently learning Python, and I've been focusing on Python3.  To try to 
kill two birds with one stone, I would also like to learn the basics of 
writing small web applications.  

These web applications don't need to do much more than provide an interface 
to a small database, and they may not even be required to be accessible 
outside of a LAN.

Does anyone have any tips on what's the best way to start off this 
adventure?


Thanks in advance,
Rui Maciel
