Try reading wikipedia.
Try looking under "modular", "coupling" and "cohesion"
You could also try "Frameworks"

Erm, I don't know what you mean by that bit?! :-)

A text file full of python functions is a module if you name it .py.
You can then import it and use the functins therein.

You don't normally execute modules, you use the executable
functions within modules. (Although in the strictest sense functions
are themselves a form of module.)

You could look at the topic on modules and functins in my tutor.
Or you could read the case study topic which uses modules
Or if you can find the paper book version (in your local library?)
you can read the Games Framework chapter which describes
how to write a set of modules (using classes) that are explicitly
designed to be extended rather than used as-is.
