Well, in my concept of MVC (opinions may vary), the controller is the
servlet, usually implemented in plain Python. The model is your generic
Python modules, usually programmed without a dependency on Webware. The
view would be a template, or if you are doing something more quick and
dirty, it may be mixed in with the servlet (often doing the controller
in awake(), and the view in writeContent()).
I prefer to pass the values around explicitly. By using higher-level
objects (defined in your model), you can pass around things like the
user, the transaction, the invoice, etc., without passing every detail
(e.g., username, invoice number, total amount, etc).
On some level everything has to be explicit, though with inheritance
(via PSP or Cheetah) the template will have access to all the instance
variables of the servlet, and you can kind of implicitly pass things
that way. But for the most part Python resists implicit passing.
