Algorithm for Labels like in Gmail

[Rodolfo]

Thanks to you all.

I'll start trying the buzhug solution, which seems more pythonic. But I
feel like I gotta learn how to use databases... once I studied SQL a
litle bit, but don't remember much.
I'll play around with Python and then I show what I got.

Bye

P.S:  Is there a way to do a "clear screen" on a Python program? I mean
something like the "cls" command in MS-DOS....
