     The os.listdir() function returns a list of all the elements  
(files and dirs, everything but . and ..) in a directory. So if it  
returns an empty list, your dir is empty.

 >>> import os
 >>> os.listdir("Prog")
['.DS_Store', 'archive', 'C-Cpp', 'docs', 'eclipse', 'gi21',  
'Haskell', 'Java', 'matt', 'ObjC', 'Python']
