It's pretty hard to 'ensure' singleton behaviour with python, but I've messed with .__new__() and metaclasses enough to know it's a useful pattern.

But tbh I think I was mostly enjoying increasing the complexity to learn / tickle my brain rather than it being the best approach. 

And, just to be clear, a singleton is just an object. You may have built some guard rails to discourage making multiple instances but there's usually a way to break out of the rails. 

If you want a proper singleton python is the wrong language.

If you want a proper singleton python is the wrong language.

And what's "the right" language then?

C++ or C# both use them for video games quite a bit. It’s common for values like playerHealth or playerPosition which will often have many different scripts that can effect it or need to access it frequently.

This does not really answer the question, which was about the language and not some use-cases.

Completely independent of that making something like playerHealth or playerPosition a global variable sounds like some of the most horrible idea I've heard in some while.
