----< showmydir.py >------------
import os
print dir()
print __file__
print os.path.abspath(__file__)
print os.path.dirname(os.path.abspath(__file__))
print os.path.join(os.path.dirname(os.path.abspath(__file__)), 'data.xml')
--------------------------------

When run, outputs (in my directory context):

[21:07] C:\pywk\clp>py24 showmydir.py
['__builtins__', '__doc__', '__file__', '__name__', 'os']
showmydir.py
C:\pywk\clp\showmydir.py
C:\pywk\clp
C:\pywk\clp\data.xml

If I go somwhere else and execute it, e.g. from a sibling directory

[21:08] C:\pywk\grammar>py24 ..\clp\showmydir.py
['__builtins__', '__doc__', '__file__', '__name__', 'os']
..\clp\showmydir.py
C:\pywk\clp\showmydir.py
C:\pywk\clp
C:\pywk\clp\data.xml

(Hm, that's an interesting outcome for __file__ )
