Spring Python 0.3.1 was released today. It contains a quick add-on feature: DecoratorBasedApplicationContext.
This feature lets you define an IoC container using python code and decorators instead of an XML flat file. It handles things like dependency injection and fetches things in order as needed. It also supports two scopes: PROTOTYPE and SINGLETON. Get it while its hot! -- http://mail.python.org/mailman/listinfo/python-list
