[2023 Day 3][Requesting Help] What am I doing wrong? (lemmygrad.ml)

I know I'm not the only one finding day 3 frustrating.

My current code for day 3 is here. I find the locations of all of the special symbols, check around them to get the numbers, and dedup the list of numbers I find. To make things easier to debug, I generated some supplementary text files. One shows the input I used, but with all of the numbers I used replaced with 'x's: the output doesn't suggest any problems with my code that are obvious. The other has each number that went into the sum on its own line. I checked a few of these numbers and they seemed correct, but there are too many to check by hand.

What could I be doing wrong? I've officially run out of ideas.

I thought my checked_coord_set already made sure numbers next to more than one symbol were only counted once.

If you’re already doing that and you’re deduping the list then you’re doing too much.
