just learning python and I'm glad you mentioned that it was basically making a tuple from the values because that's what I was thinking to do before watching the vid :)

Just keep in mind that, despite it looking like a single operation, this operation is not atomic in Python. You still need a lock if you are swapping variables that are being accessed by multiple threads.

Python is cool ... but here, is this cool, or is it superior?
In terms of the code, it looks simpler, cleaner, that is for sure.
But, behind the scenes, let say you have to do it a million times ... is it slower, the same, faster.
I have no idea what goes on behind the scenes with Python, and I would like to find out, but
I'm thinking here, this doesn't make much difference.
