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

def files_gen(topdir='.'):
    for root, dirs, files in os.walk(topdir):
        # ... do some stuff with files
        for f in files:
            yield os.path.join(root, f)
        # ... do other stuff

for f in files_gen():
    print f
