Question

Is it possible to append elements to a python generator?

I’m currently trying to get all images from a set of disorganized folders and write them to a new directory. To get the files, I’m using os.walk() which returns a list of image files in a single directory. While I can make a generator out of this single list, I don’t know how to combine all these lists into one single generator. Any help would be much appreciated.

This should do it, where directories is your list of directories:

import os import itertools  generators = [os.walk(d) for d in directories] for root, dirs, files in itertools.chain(*generators):     print root, dirs, files
