You need to read up on subclassing builtin types and/or describe what you want to achieve. str is an immutable type, and so you must return an instance from __new__. Read this: http://www.python.org/download/releases/2.2.3/descrintro/ And here is an example that might get you started (assuming you really want to do this): class StupidDefaultString(str): default = "I'm a Default!" success = "42" error = "Not a default, don't bother." def __new__(cls, arg=None): if arg is None: arg = cls.default return str.__new__(cls, arg) def __str__(self): if self == self.default: return self.success else: return self.error py> s = StupidDefaultString('Bob') py> s 'Bob' py> print s Not a default, don't bother. py> s = StupidDefaultString() py> s "I'm a Default!" py> print s 42 James -- James Stroud UCLA-DOE Institute for Genomics and Proteomics Box 951570 Los Angeles, CA 90095 http://www.jamesstroud.com/ -- http://mail.python.org/mailman/listinfo/python-list
