I see a couple of problems with your code: 1. where is n first given a value and what is it total file count, etc? also you decrement the value, do you want the last file in the directory or something? 2. The if os.path.isdir(full_path): .. findFile(full_path) part doesn't return or handle the value so it's not useful so far i can see. So you either need to "return findFile(full_path) " or "value = findFile(full_path)" 3. I am not sure of your usage of n, the way i do similiar things is to build a list and then just get the item i want by index or slicing.
