	There are a few ways of doing this.  

	* os.listdir(path) returns a list containing the names of all
the files in the directory specified by path.  

>>> import os
>>> os.listdir('.')
['Group.java', 'Group.class', 'User.java', ... ]

	So you can do os.listdir('C:/whatever/sub/dir/ectory'), and
then loop over each filename with a for loop.

	* The glob module returns a list of filenames matching a
wildcard pattern.  

>>> import glob
>>> glob.glob('*.java')
['Group.java', 'User.java', 'GroupWrapper.java', ... ]
