Command Line arguments in Python using the sys module

It seems like our man is here doing a fantastic job showing us how to get this done, but I'm not sure I understand what exactly it is we're doing here. Could anyone explain this to me? Any help would be appreciated, thanks.

Bruh this is the only good english tutorial that isn't 7 years old, You're the bomb mate cheers

Hey, you're awesome. 👍🏾

It might be a REAL GOOD IDEA to post the code

That might be a great editor but I can't see a thing on your screen.

You speak very clearly but the typed text is so small, pale, and blurry that I can't see it.

run your code from Visual code is easy download compiler

nice.
