@pacmaninbw Not a lot, but a statement that it is expected to take input from the user in some manner and produce some set of meaningful outputs would be nice. I agree its fairly 'obvious' what is going on, but I think it is important to insist on high standards for all questions, because it is a learning experience for the OP, and means we don't have lots of examples of "Title + code" for people to point at when we unanimously close them for lack of clarity.
It also gives us some confidence that the code works, and we aren't just going to end up with an answer explaining it doesn't work and have to close it anyway, and all the related issues like that.
(I'm very fond of questions which explain how the code works, because it makes it easier to understand and indicates they actually understand it, but I don't know that should be a requirement)

I suspected as much. I think that makes this a really broad question. You haven't identified anything that's actually wrong with your code (other than "I dont believe its the best by a long shot", but what does that mean?) and you haven't identified what specific improvements you're seeking to make, so I'm not sure how this is really answerable.
