And it didn't. It seems something implemented in 3.10 according to the other commentary. I used this in C# and Java, but didn't tried in Python just thinking it hadn't it.

i liked this - this is how i done it. Although i think i may have been bias; been coding a few years in python and would not have consided looking into a switch function or similar. I've been brushing on C++ and CUDA over the past few weeks and made be try what i would consider doing in C++. Which also makes me wonder, how does this solution stack in terms of execution time and memory compared to others. Anyone done any profiling on it?

it came with python 3.10

I would guess that missing dot at the end is a problem
