It seems that some of your terms are mixed up so it's hard to know what you
might be referring to. Modules aren't callable, and are a container usually
representing objects parsed from a file loaded into the interpreter (but
there are other sources).

Do you actually mean global variables in a module? Or do you mean local
variables created within a function that lives within a module?

Variables created in the global scope of the module will live for as long
as the module stays loaded in the interpreter. This is really just a fancy
term for it living in sys.modules, and also once no one keeps a reference
to it.

Variables created in the scope of a function body are local to that
function and are destroyed when the stack frame of that function call is
cleaned up, at the end of the function.
