First, property() only works when attached to classes, not instances. So the assignment should be: B.testattr = property(...) Second, the property() call in you example only defines a getter function (the first argument) and not a setter function (the second argument) it defaults to a read-only property. That is why b.testattr='test' would still fail. Raymond -- http://mail.python.org/mailman/listinfo/python-list
