The __file__ attribute is present when you run a script from a file. If you run from the interactive interpreter, it will raise a NameError. Likewise, I believe that in earlier versions of Python (2.1? Pre 2.2?) it was only set within imported modules. I've used the 'os.path.realpath(os.path.pardir)' construct in a couple of scripts myself. That ought to work within the interactive interpreter.
