parse text files in a directory?

[jo3c]

hi everybody
im a newbie in python, i have a question

how do u parse a bunch of text files in a directory?

directory: /dir
files: H20080101.txt ,
H20080102.txt,H 20080103.txt,H2 0080104.txt,H20 080105.txt etc......

i already got a python script to read and insert a single text files
into a postgres db.

is there anyway i can do it in a batch, cause i got like 2000 txt
files.

thanks in advance

>>import os
for filename in os.path.listdir (directory):

.... if is_interesting( filename):
.... do_something(fi lename)

you'll have to implement is_interesting( ) to catch filenames
you're interested in and you've already implemented the
do_something() body.

You might want to look at the "glob" module which allows for easy
filespec testing and name expansion for your "H*.txt" format:

for filename in glob.glob('H*.t xt'):
do_something(fi lename)

If they're in subdirectories, you may want to investigate the
os.walk() generator which will walk the directory tree and allow
you to do something with the files:

for path, dirs, files in os.walk(directo ry):
for filename in files:
filename = os.sep.join(pat h, filename)
if is_interesting( filename):
do_something(fi lename)
