It might be becoming 'long', but this discussion contains much of profit to many people! Us 'silver surfers' do need to periodically question those beliefs we hold as 'tenets' of ComSc. Amongst them is RAM (or "core"!) conservation. It remains a virtue somewhat, but at the same time, storage

I agree with you, so I'm going to ignore def branch2(a, b, z): and def branch3(a, b, z) because they appear too contrived - and I guess that's fair, in that you've contrived to satisfy pylint. Question: are there other people/factors who/which should be regarded as more important than the lint

Friday Finking: Source code organisation

Is it helpful to, and thus, do you have a style/convention for ordering the methods within each class in your code? Python's "honking great idea" of namespaces enables us to gather functions/methods under a single name-umbrella, thereby avoiding name-clashes/name-space 'pollution'. [Oh yeah!]

Re: Friday Finking: Source code organisation

"Define before use" is a broad principle that I try to follow, even when the code itself doesn't mandate this. IMO it makes the code easier to navigate even when it's not strictly necessary. As others have said, Python mandates that the functions be defined before they're CALLED, but I find that
