Hi! My head crashed into this: >>> class C(object): ...: pass ...: >>>>>> dir(C) ['__class__', ...] >>> C.__bases__ (<type 'object'>,) Why __bases__ does not appear in dir()? Is there a good reason for this or should I file a bug? Thanks! -- . Facundo Blog: http://www.taniquetil.com.ar/plog/ PyAr: http://www.python.org/ar/
