Yes, you are correct however for the rest of us who wish to understand the specific mechanisms for building a command line there lies my article.

For instance, for many years I used argparse and got reasonable results but I was always wanting to get that library to do things it seemed unwilling to do and so sometimes I wish to roll it myself because it is easier than learning the internals of someone else’s work.

Thanks so much for taking the time to leave a comment. You are awesome.
