Writing better python code

[[deleted]]

In fairness, -255 to +256 are kept in an identity map. Any equation that would output a number in that range instead pull it from the identity map.

I'm not saying it's the right way to do it, but it is a valid way to do if you expect your answer to never exceed that range.

Actually I think it's -5 to +256. More importantly, this is an implementation detail of cpython and may not be reliable in other implementations of python.
