Summary for those just joining us:
Advent of Code is an annual Christmas themed coding challenge that runs from December 1st until christmas. Each day the coding problems get progressively harder. We have a leaderboard and pretty good turnout, so feel free to hop in at any time and show your stuff!
Whether you have a single line monstrosity or a beautiful phone book sized stack of OOP code, you can export it in a nice little image for sharing at https://carbon.vercel.app

Part 2 was a pain in the arse today, but there are two ways I could imagine solving it:
shapely
is a fairly good library for this.I went for the latter, which is a bit slow but far less memory intensive.

Part 1 was really easy, so I was kind of figuring part 2 was going to throw a curveball. I did not expect it to be that much of a b-word to figure out on day 10 though. I also eventually did a polygon type solution, but if I could go back in time, I think I would have done the flood fill you mentioned instead. I probably could have saved myself a couple frustrating hours.
