Grok is a Python framework that runs on top of Zope 3 and focuses on agile development. The Grok framework uses Adapters for making it possible for existing objects to conform to specific APIs without the need to modify them [j.mp/grokada].
The Python Traits package also uses the Adapter pattern for transforming an object that does not implement of a specific interface (or set of interfaces) to an object that does [j.mp/pytraitsad].
