For smaller projects don't bother. For large projects Zope Interface seems to be popular: http://wiki.zope.org/Interfaces/FrontPage PyProtocols is similar but no longer actively developed: http://peak.telecommunity.com/PyProtocols.html A different approach, perhaps more Pythonic, is for consumers to check what kind of thing they are given. One way to do this is here: http://oakwinter.com/code/typecheck/ You might also be interested in http://www.python.org/dev/peps/pep-0246/ http://www.python.org/dev/peps/pep-3107/ Kent _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
