[Tutor] Reading matching text files in a folder

[Lloyd Kvam]

Some code snippets to help:
>>> flist = os.popen("dir *.py /B").readlines()
>>> flist
['class_test.py\012', 'fib.py\012', 'fnx_counts.py\012', 'ia_test.py\012', 'lloyd_util.py\012', 'localhost_8000.py\012', 'parkAP.py\012', 'parkCGI.py\012', 'parkCOM.py\012', 'park_test.py\012', 'pos.py\012', 'resv.py\012', 'sqrt_sum.py\012',
'testdict.py\012', 'testresv.py\012', 'three_n_plus_one.py\012', 'ui_dict.py\012', 'util.py\012']
>>> import DateTime
>>> xdate = DateTime.Date(2001,3,15)	# the ides of March, 2001
>>> xdate.day
15
>>> xdate.day_of_week
3

Programming Python (Lutz) devotes chapter 2 to covering System Tools: reading directories and processing files.

DateTime is from mxDateTime a very complet package of date and time handling tools.
