[Tutor] Practice sets for newbies

[riex@ligbr.com.br]

Hello, tutor,
I wonder if there are any practice tutorial sets for things like 
loops,lists, the use of modules, and etc. 

I'm new to python, and programing in general. So far I have used Josh 
Cogliati's "non-prog. tutorial for python", and also Guido Van Rossun's nice 
"python tutorial" to get me started. 

However, I think that having some basic practice problems could take me a 
step further.
Does anyone have a tip for me on how to improve my python skils ? 

All the best to all, Diego.
