If it's just a completely dumb struct-like class, you might consider something like: http://docs.python.org/library/collections.html#collections.namedtuple > What is "best practice" for implementing this sort of class > *succinctly* (i.e. without a lot of repetitive accessor code)? Is there any good reason you can't just use straight instance variables?

Yes, using the magic of the property() function: http://docs.python.org/library/functions.html#property Cheers, Chris -- http://blog.rebertia.com -- http://mail.python.org/mailman/listinfo/python-list
