pykattis

A CLI tool for solving Kattis problems with python.

Installation

pip install pykattis

Usage

To create a solution for a problem, run:

pykattis create {problem_id}

where problem_id is the Kattis problem ID. This creates the directory problems/{problem_id} in the current working directory with the files solution.py, an __init__.py file, and downloads the sample input-anwer pairs to a samples.json file.

The solution.py-file is where you will be writing the solution to the problem. Inside it is a function solve(input_: str) -> str:, which you will fill out with your program as you see fit. This function is called by the commands kattis run and kattis test.

To simply run the program as a script, run:

pykattis run {problem_id}

and to test it on the sample input-answer pairs defined in samples.json, run:

pykattis test {problem_id}

To upload the solution to Kattis, you can submit the problem's solution.py file through Kattis's web form. However, this is a temporary solution. In a future version, you will be able to publish your solution to Kattis directly through pykattis.

If you, for some reason, just want to download a problem's samples, you can run:

pykattis download_samples {problem_id}

It is recommended to use a VCS, like git, to keep track of your solutions.
