[Tutor] interfaces and abstract classes in python

Interfaces and abstract classes - I know they don't exist per se in Python. But what are the closest analogues? I've found a few examples, e.g. for an abstract class the following page has a fairly common suggestion: http://www.norvig.com/python-iaq.html thanks! alex _
