I've been teaching myself Python at my new job, and really enjoying the language. I've written a short class to do some basic data manipulation, and I'm pretty confident about it. But old habits from my structured/modular programming days are hard to break, and I know there must be a better way to write this. So, I was wondering if any...

From what I understand, Pylons is more of a 'bare bones' framework (where you can choose your ORM and template engine), and Django is a little more rich in nature. What exactly are the features/frameworky elements that Django has that Pylons doesn't? (other than its own ORM, and its auto-admin page generation) ...

This achieves cross-platform support at the cost of having widgets that don't necessarily look, feel and behave exactly like their native counterparts. ...
