The discussion you're talking about was *not* to say “attribute access is better than dictionary access”, or vice versa. Each is good for its purpose. Rather, the discussion was to drive home the point that in Python those are *two distinct concepts*, and you need to not conflate them. If you want items in a mapping, explicitly use a Python ‘dict’ instance. If you want attributes that describe an object, explicitly use attributes of that object. Deliberately choose which one makes more sense. -- \ “The double standard that exempts religious activities from | `\ almost all standards of accountability should be dismantled | _o__) once and for all.” —Daniel Dennett, 2010-01-12 | Ben Finney
