This repository contains my own solutions to the Advent of Code coding puzzles.

Spoiler alert!

If you don't want those puzzles spoiled for you, don't look at the code! It runs on Python 3.10+.

The puzzle-solving code is all purely Python Standard Library stuff. The only external dependencies are optional:

• rich, for pretty printing on the console, and
• pillow, for rendering visualisations.

Execute advent.py at the top-level of the repository, with the year and day number.

./advent.py 2023 9

You can give the -t/--test argument to run the test case from the puzzle explanation instead of the actual puzzle, -v/--verbose to enable debug logging, or -d/--draw to output a visualisation (if the puzzle code supports that).

Here's a sample of some of the visualisations I generated for these puzzles:
