[Tutor] ok, I want to read a dir.

[Kirk Bailey]

Say, looking this over, FILTER looks like a good candidate for this job.


files=os.listdir('./lists/')            # this creates a raw dir listing
filelist=[]                             # create an empty list
fnmatch.filter(filelist, "*.info")      # return the subset of list
which match!

this is not right, but close. What is the right way to use fnmatch and
filter?
This is the error I get:

ns# ./TLpost.py
Traceback (innermost last):
  File "./TLpost.py", line 189, in ?
    listname = sys.argv[1]
IndexError: list index out of range
ns# 

And that puzzles hell out of me.
