Can you provide a Python code to print fname given the following:
I wrote the below code

    os.mkdir('bgs')
    t = tarfile.open(name=archive_name)
    def members():
        m = t.next()
        while m:
            (yield m)
            m = t.next()
    index = 0
    for m in members():
        if (not m.name.endswith('.jpg')):
            continue
        f = t.extractfile(m)
        try:
            im = im_from_file(f)
        finally:
            f.close()
        if (im is None):
            continue
        if (im.shape[0] > im.shape[1]):
            im = im[:im.shape[1], :]
        else:
            im = im[:, :im.shape[0]]
        if (im.shape[0] > 256):
            im = cv2.resize(im, (256, 256))
        fname = 'bgs/{:08}.jpg'.format(index)
        print fname
        rc = cv2.imwrite(fname, im)
        if (not rc):
            raise Exception('Failed    to    write    file    {}'.format(fname))
        index += 1

What's a good function header?
