Writing script arguments and filtering images

We want to write a script that will take a list of images and will produce a single panorama picture. So, let's set up the ArgumentParser for our script:

def parse_args():    parser = argparse.ArgumentParser()    img_group = parser.add_mutually_exclusive_group(required=True)    img_group.add_argument('--image-dir', type=Path)    img_group.add_argument('--images', type=Path, nargs='+')    args = parser.parse_args()    if args.image_dir:        args.images = sorted(args.image_dir.iterdir())    return args

Here, we created an instance of ArgumentParser and added arguments to pass either an image directory of a list of images. Then, we make sure we get all the images from the image directory if it is passed, instead of passing ...
