You're right but first of all I wrote what I'd like to do and if Python 
could be the best choice about it! :)

Ahaha! I think you know what is spam and what is a reply\answer to a 
post request so you can feel free to use also my email! :)

You got the point!

Like what I wrote above I didn't know if Python can does what I need and 
if to use Python is a good way I'll start to study how to do it! :)

In my past I used Python for Arduino programming or to do easy things, 
what I should do now is little more complex but I understood from years 
and years by the Python's powers you can do everything! LOL! :)
