I'm a newbie too. Just to be perfectly clear about this, if you have a
half-dozen modules in an application, and you import Sys in everyone of
them, I am going to assume that Python will only load one instance of Sys.
When it hits the import statement to load Sys in the other modules, it knows
that Sys is already loaded and will simply create a link to the already
Is there any way to unload a module after you're finished with it and will
absolutely no longer need it?
