The paper doesn’t use psuedocode as I know it. In my experience pseudocode looks much more similar to real code. (According to Wikipedia I’m more used to mathematical pseudocode)
I’ve never been a fan because writing some simplified Python seems better. Or even better, writing Python that doesn’t necessarily follow every syntax rule to a T and takes liberties where necessary to improve readability
