PureMVC and Python

I'm rewriting an application I worked on about a year ago in Python.  It's a flashcard app which uses a randomized-picking algorithm on top of Leitner's memorization system.

Does that sound pretentious?  It's not :)  But it's a pretty easy system.  The app has a list of cards (questions/answers) which it places in buckets, according to how many correct guesses the user achieves.  As the user guesses better, the cards are displayed less often.

I wanted to replace this with a time-based algorithm; randomization kinda misses the point of Leitner's system.

Anyway, since I'm doing this in Python, and I'm such a big fan of PureMVC, I wanted to give it a try in a dynamically-typed environment.

It works really well.  I'm still wiring things together, and working on some tweaks to the UI.  I'm hoping to have a functioning copy to post on SourceForge.
