>>> import os
>>> # Because I work under MSW I took backslashes instead of slashes
>>> # But you can take os.sep, which is os-independant
>>> path=r'\home\sdhyok'
>>> #file is not a good name, because it is a builtin-function
>>> lfn='data.txt'
>>> path_file=os.path.join(path,lfn)
>>> print path_file
\home\sdhyok\data.txt
>>> print os.path.dirname(path_file)
\home\sdhyok
