Yes, however that's (1) likely slightly slower due to the global lookup for the class name (2) brittle WRT inheritance; subclasses can't override the value (3) brittle WRT class renaming/refactoring, unless you use self.__class__.CONSTANT, which is uglier Cheers, Chris -- http://blog.rebertia.com -- http://mail.python.org/mailman/listinfo/python-list
