What sample application demonstrates best practices for MVC structure in a Google App Engine/Python app?

Although I know the Python language, I've never buil开发者_JS百科t a significant web app containing a large number of classes.

Now that I am contemplating doing so, I am questioning how best to structure the code in an organized way as I would normally do in a Java application.

Are there any sample Python web apps for App Engine that provide a good example of large-scale code structure?

I recommend checking out Bloggart and rietveld.

For more, here's a list of App Engine samples, a big list of open-source App Engine projects, and another one.

rietveld, by Guido van Rossum (Python creator) is a Django app built on GAE and is a good one to check out.
