That code is pretty version specific:

In older versions of Python you may have to convert __main__.__file__ to an 
absolute path (I'm not sure what 2.6 does as I don't have it to hand, but 
2.5 and earlier could have a relative path).

In Python 3.x the print will break.

Also, any version can also fail if the code using it is called from an 
interactive session as __main__ doesn't always have a __file__ attribute.

So for the paranoid you might use:

  print(os.path.dirname(os.path.abspath(
    getattr(__main__,'__file__','__main__.py'))))

which falls back to giving you the current directory from a script (and 
might be what you want if you haven't changed it since the script started).
