A little assistance with os.walk please.

Yes.

 >>> for path, dirs, files in os.walk("."):
...     for f in files:
...             if not f.lower().endswith(".txt"): continue
...             print os.path.join(path, f)

If you want to be more complex:


 >>> from os.path import splitext
 >>> allowed = ['.txt', '.sql']
 >>> for path, dirs, files in os.walk("."):
...     for f in files:
...             if splitext(f)[1].lower() not in allowed: continue
...             fn = os.path.join(path, f)
...             print "do something with %s" % fn


Just a few ideas,
