The problem with Java is that it makes it very painfull to bridge two APIs together, while Python usually makes it a breeze (easy delegation, no dumb-ass psycho-rigid type system). So Java's solution (hyper-formalization) isn't necessary here. Now there's something along this line - just much more useful and flexible IMHO - in Zope3 and Twisted. You may want to look at Zope's "Interfaces" for more infos on this, or to read this post by the BDFL: http://www.artima.com/weblogs/viewpost.jsp?thread=155123 HTH -- http://mail.python.org/mailman/listinfo/python-list
