[Tutor] Built-in modules

[Alberto Troiano]

Hey tutors

I have some classes I want to make available as built-in modules in Python 
2.3.4 over Windows
To make myself clear in case you don't understand I have the file List.py (a 
nested list C# like) and I want to be able to call the class List (which is 
inside the List.py) without having to copy it in every folder where I have a 
script that needs this module

Can I do that?

You see I googled about it but it seems I'm not using the right words.

Best Regards

Alberto
