Solutions for Advent of Code 2021 in pure Python 3.9. 🎄 No dependencies, no speed hacks: pythonic code with just the standard library. 👍 Well, unless I'm too annoyed by the challenge of the day. 🤪
Starting at day 5, the code includes comments on coding patterns and algorithms. 📝 This should keep the code understandable even for people new to Python or not familiar with the specific algorithm. 🤔
There are no solutions for day 24. 😢 It's a nice puzzle but not exactly a coding challenge without diving deep into logical solvers. 🤷
The module is directly executable from the CLI. Daily input data is searched inside ./data/ named dayXY.txt or dayXY_ex.txt for examples.
# run day 3
python3 -m aoc2021 3
# run day 4 with example code
python3 -m aoc2021 4 -e
# run days 1,2,3,4,5
python3 -m aoc2021 1 2 3 4 5
# show available options
python3 -m aoc2021 -hUse the --data switch to point to a custom data location.
The module can be installed to allow running it with aocd. This lets you compare its solutions against your own and others.
