>>> import os
>>> for filename in os.path.listdir(directory):
... if is_interesting(filename):
... do_something(filename)
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*.txt'):
do_something(filename)
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(directory):
for filename in files:
filename = os.sep.join(path, filename)
if is_interesting(filename):
do_something(filename)
