import os

file_list = open('file_list.txt', 'a')

for each_file in os.dir('/var/path/to/files/'):
    print each_file
    file_list.write(each_file)
    file_list.write('\n')

file_list.close()

print 'done'


Here, I'm assuming you want to APPEND the names of the files,
one per line, to the textfile whose name you indicated.

Also, I'm assuming that you want to see subdirectories (if any)
as well as files.

It's trivially easy to make each of these assumptions in some
OTHER direction, of course, but, unless you give precise specs,
people who try to help you will have to just take their best
guesses at what you might have meant.
