This is a good use-case for a lambda. Ethan's use-case is a dict of constructors: fielddef = { 'empty':some_func, 'null':some_func } There's no need to expose the constructor outside of the dict, hence: fielddef = { 'empty': str, 'null': lambda: None } does the job. No need for a top-level named function. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
