Additionnaly to redblobgames's guide others mentionned, romlok already made an implementation of redblobgames's math into godot's GDScript : https://github.com/romlok/godot-gdhexgrid It works great, you don't have to use it but I guess studying the mechanics could help if you want to rewrite it in python. You get almost everything hex related : distances, barriers, path finding, directions, etc.
