Output Not Changing When Arguments Used

[jnewmaster]

Operating System: Windows 10
Python: Python.org 3.8.5

When trying to run script with arguments, it shows the same output as it would without any arguments.

I am not very familiar with python so I am unsure what may be the issue here.
The only thing I did non-default was install python for all users in Program Files and not in AppData.
Edit: I tried installing in AppData as well and had the same issue.
