The orientation calculation could be done by matrix indexes operations https://github.com/FlakM/aoc2021/blob/main/day5/task1/src/main.rs and then its easier to create ranges. You can also use some clever crates and get some calculations for free https://github.com/timvisee/advent-of-code-2021/blob/master/day05b/src/main.rs

Python day 17 solution (GitHub). Not the fewest lines of code, but used dataclasses and modular functions to try improve readability -- I got very confused with keeping track of indices of velocities vs coordinates in other people's posted solutions. I find dataclasses in Python can be a great way to be descriptive about the quantities you are iterating
