For a notebook I would ask the user to change a filepath variable in one of the top cells.

But I'm also a stupid data scientist.

What do you propose as the long-solved solution?

I'd propose reading data from stdin. Seeing this is about python, one could even consider using fileinput [0] to manage multiple files.

It is a jupyter notebook, not a python script. Your proposal won't work.

You generally don't open a notebook from the commandline, you open it from the notebook file picker inside your browser.

You generally don't "run" a notebook, like you would a script. It is an interactive programming environment.
