Advent of Code 2021

I took part in Advent of Code, a series of coding challenges throughout December. However, I very quickly got sidetracked. Instead of completing the entire month, I spent most of the time learning about unit tests (pytest), type hints in python (mypy), writing documentation (with sphinx), linting (flake8) and using github's CI.
