[Python] Does ArgumentParser support different arguments per file, ffmpeg style?

I want my application to work on several files and have a different set of options for each input file:

python my.py -a file_a -b file_b --do-stuff=x file_c


ffmpeg uses this idea for its command line arguments.

I tried the following:

parser = argparse.ArgumentParser()
parser.add_argument("-a", action="store_true")
parser.add_argument("-b", action="store_true")
parser.add_argument("--do-stuff", type=str)
parser.add_argument("files", type=pathlib.Path, nargs="+")
args = parser.parse_args()


And I get an error:

error: unrecognized arguments: file_b file_c


Can I use ArgumentParser to parse such a command line?
