The error is not with the Python code but with the way you are
running the script.

It is telling you that you need to provide a file argument.
Something like:

C:\WINDOWS\PROMPT> python D:\Python\myscript.py D:\Image\myfile.img

That's what all the argparse stuff is there for, to ensure
that Python can read and understand the arguments that
are passed when you run the script.

The script as it stands does nothing except check the arguments.
It does nothing with those arguments.
