I would use os.walk(), with fnmatch.fnmatch() to do the pattern
matching, and write the function as a generator (using yield). It
would look something like this (untested):
import os, fnmatch
def findFiles(topDir, pattern):
for dirpath, dirnames, filenames in os.walk(topDir):
for filename in filenames:
if fnmatch.fnmatch(filename, pattern):
yield os.path.join(dirpath, filename)
To get a list of matches you would call
list(findFiles(topDir, pattern))
but if you just want to iterate over the paths you don't need the list.
