Adding elements to python generators

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

Answer 1

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
