Command Line Arguments
Can someone explain to me the concept of the command line, and what it means to be running from a command line argument in python?
The 'command line' is referring to a way of interacting with the files and programs on your computer in a text-based (as opposed to graphical) manner. How you access it depends a lot on what kind of system you are using. Here is a crash course if you want to learn more about the command line in general.
(I know I just linked to LPTHW, which is frowned upon in this subreddit, but his command line crash course is genuinely quite good for beginners and is free. Please no one freak out.)
Also, is there a reason that when I try to execute a program, it creates a window that closes almost immediately?
Yes, this is a thing Windows does. It thinks the program is all done, and 'conveniently' closes the window for you. Try adding an input() to the end of your code to keep the window open, or run your code from the command line.
aspects of a code outside of the syntax, such as how the computer knows how to read it, and how it's meant to interact with other programs
That's a pretty broad question, but here's a stackexchange answer that might be relevant.

Command line arguments are inputs provided to a program when it is executed from a command line interface (CLI). These arguments, typed by the user alongside the program's name, enable the program to perform specific tasks or operate in different modes. By allowing input data or options to be passed, command line arguments customize the program's behavior without altering its source code.
