What do you mean, "objects are saved in another object"?

What happens if the user launches appwin with a different argument?
If appwin can only take one, compulsory, argument, then it's silly to
require it as an argument. Just have appwin automatically import user.py,
and do whatever it needs.

This makes no sense to me. Are you saying that appwin opens a text editor
that allows the user to edit the user.py source code?

Making them a single module still retains the option of console or many
different window interfaces.

I don't know. How does user.py create the objects? Suppose it users a
function called "create". Then you would do this in appwin:

What do you mean by "view() is encounted"?
How would you access the objects stored in doc.py? Suppose you access
them using a list called "list_of_objects". Then in appwin.py:
for obj in doc.list_of_objects:
where you have to write the function "do_something_with", to do whatever
it is you want to do.
By the way, calling a module "doc" which is not for *documentation* is a
