Learning with Open Source Applications.

[Jorge Biquez]

Hello all.

I am sorry for the cross posting but I really would like to hear 
comments from experience people in Python.

I am new to Python, not new in programming. I am leaving the PHP path 
and moving to Python. When I was learning PHP it was very useful to 
learn to install OpenSource solutions , implemented them and study 
how they work, learn how to modify them. For example I used 
e-commerce shopping cart solution and learned a lot.

Can you recommend, similar solutions, not only for shopping cart but 
any other subject is good also so I can follow the same schema of 
learning ? I mean, solutions you consider are very well written and 
that are examples of what a good Python applications should be 
written? I know there are tons of applications but would like to hear 
advice based on experience if possible. Thanks.

Thanks in advance.
