Advent of Code 2020: Problems solved with Python

These are my answers for the Advent of Code 2020 challenge. I use Python as my main programming language for this exercise.

Overarching goal: show novice users some good Python code examples.

Having been programming in Python for a few years now, I have learned a lot about how to write nice, readable and correctly working Python programs. I am by no means a Python guru, just somebody who likes to share lessons learned. If you see some solutions that can be improved, feel free to make a PR!

Goal: show off the stdlib

Python has many useful builtin features or functions that can be used to solve problems as stated in "Advent of Code". I hope to highlight these features by solving the problems and hope this encourages people to read the Python documentation more when they are trying to tackle a problem.

Goal: provide functional programming examples

The programs follow the functional programming paradigm as much as possible. The functions should return the same output when given the same arguments. There is no internal "state" to take into account. This simplifies testing and code maintenance.

Goal: provide examples for testing

All programs are tested using pytest. This ensures that they work before the solution is submitted. It also shows new users how to write a few simple tests.
