Thanks Peter,
You are right, I have to try to touch the Python but the problem is I
don't have much time to do so.
I have a Java developer for more than 4 years and I find it is not so
easy to digest Python concepts, this is why I'm asking a lot of
obvious and clear easy to you (long time Pythonists).
Thank you for your time.
