Advent of Code

My solutions to Advent of Code.

All solutions are written for Python 3.9+ and use only standard library utilities.

All solution files can be executed without arguments on the command line. The script will try to find a matching input file under the input directory relative to the script. E.g. ./2023/day01.py will try to read ./2023/input/day01.

$ python3 2023/day01.py
55002
55093

You can also specify the input file as an extra argument:

$ python3 2023/day04.py example
13
30

util.py

The util.py module contains common helper functions used in the solutions.

download.py

The download.py script can be used to download input files from adventofcode.com. It requires an active session key ot be stored in the sessionkey file.

The script will also create a template for the solution file if non already exists.

$ python3 download.py 2023 10
Fetching input file /Users/pnystrom/Projects/advent-of-code/2023/input/day10
Writing empty solution file /Users/pnystrom/Projects/advent-of-code/2023/day10.py

runall.py

The runall.py script can be used to execute all solution files in the repo (that there are input files for):

$ python3 runall.py
day01a.py: 888331
    (0.005 s)
day01b.py: 130933530
    (0.102 s)
day02a.py: 378
    (0.004 s)
day02b.py: 280
    (0.006 s)
day03a.py: 195
