Solve sudoku puzzles, obviously.
Download this repo as a zip, or alternatively clone it. Run the solver, sudoku_solver.py. It will attempt to solve all 291 puzzles in sudoku_puzzles.py. Currently, it solves 214 of them.
A sudoku solver and a verifier, for sanity's sake.
I welcome any suggestions you may have. I emphasize suggestions because I'm trying to work this out for myself, rather than copy and pasting other people's solutions. I'm just trying to further my understanding. Until I solve all 291 via my solver, this is strictly a one-man operation. Feel free to fork it and modify it, though. I wouldn't mind that at all.
I know my code is cluttered. It'll probably be that way until it's 100% functional. Then I'll clean it up.
