This is wrong. There are packages & modules in python.

And please *don't* do put one class per module, as you would do in Java! 
Instead, group related classes into modules, breaking them up into 
several submodules if size or differences in usage suggest so.

The MVC pattern is more important in terms of actual classes written, 
not so much regarding their distribution over a set of files. If you 
want, start with one big single module inside a application-naming 
package - or even no package at all. Split up if you need to.

Or just go for

<mypackage>/__init__.py
<mypackage>/model.py
<mypackage>/view.py
<mypackage>/controller.py


if you *must*.
