These are my solutions to the annual Advent of Code puzzles.

These are not by any means exemplary or optimal solutions. Mostly, I've done enough in each case to solve the problems in a reasonable period of time, tidied up the code a little and stopped there. Additionally, some problems remain unsolved.

Everything is in Python 3. The code has doctest style tests as they are quick and easy to write when working on a problem.

The code is under the advent module with each year having its own submodule. Common code for each year is in the submodule and general utilities are in advent.

Each day is a separate submodule called day<n> under each year. When executed they will output the answers to the standard output. The day modules will usually contain the following functions:

• main - the entry point
• part1 - solves the first part of the problem
• part2 - solves the second part of the problem
• read_input - reads and parses the puzzle input

The input directory contains copies of the input for most days (which will be specific to me).

The template.py file is a template for quickly creating a script for each day.

There is a CI pipeline that runs the tests, lints the code and checks its formatting.
