Python Advent of Code 🎄

A Python CLI and library for interacting with the Advent of Code API.

Key Features

• 🌐 Opens the daily puzzle page in your browser
• 🚀 Downloads your personalised puzzle inputs
• 📂 Generates new solution files from a template
• ✅ Tests and directly submits your solutions

Installation

To use the project, you can simply install it using pip:

pip install python-aoc

It can then be used in the command line and imported as a library with pyaoc.

Configuration

To interact with the Advent of Code API, you must provide your session token. This tool reads the token from an environment variable named AOC_SESSION, which must be set before use.

To verify that your session cookie is set up correctly, you can display it using the following command:

pyaoc session

Quick Start

The most common workflow is to create, test, and submit a solution.

1. Create the files for a new day:

   The following command will create a day-5/ directory, download the input into day-5/input.txt, create a day-5/test.txt file to hold a test input, and create a day-5/main.py script file from the default python-aoc template:

   pyaoc create 5 2025
   

2. Test your solution against a known answer:

   Once you have completed your solution to the puzzle, written in a solve function which takes in the path to an input file, you can test it against a known answer for an example case in test.txt:

   # Assuming the example answer is 123
   pyaoc test day-5/main.py 123 --test-input-path day-5/test.txt
   

3. Submit your final solution:

   Then, the final solution for the specified part can be submitted using the submit command:

   pyaoc submit day-5/main.py 1 --day 5 --year 2025 --input-path day-5/input.txt
   

For the complete list of CLI commands and their arguments, run pyaoc --help.

Library Usage

You can also import and use the core functions in your own Python scripts:

import pyaoc

# Sets the session token for this script
pyaoc.set_session("your-session-token")

try:
    # Get puzzle input for Day 1, 2023
    puzzle_input = pyaoc.get_day_input(day=1, year=2023)
    print(puzzle_input[:50]) # Prints the first 50 characters
except Exception as e:
    print(f"An error occurred: {e}")

Development Setup

This project uses uv as a package and virtual environment manager. To set up the project for development, follow these steps:

1. Clone the repository:

   git clone https://github.com/benjaminrall/python-aoc.git
   cd python-aoc
   

2. Run the application using uv:

   uv run pyaoc
   

   This will automatically install any required packages and run the command in a virtual environment, including any changes to the source code.
