A python implementation of a build calculator for League of Legends.

See example.py for examples on how to use the code, which you can use by running python example.py.

Mastery data is stored in resources/patch_number/mastery.json. If you find errors, let us know or send us a pull request with the updates. Note that as long as the masteries have not changed, previous patch data may still be correct.

To install, clone the repository (or download the zip and unzip the contents) into a folder of your choice and run python setup.py

While you add (or edit) your PYTHONPATH, you can also create a new environment variable called DEV_KEY and set it to your Riot API development key. This allows you to run python example.py without inputing your API key, because example.py will read it from your system.

Dependencies include Cassiopeia and python's tabulate module. You can pip install both of these, but if you want to ensure you have the most up-to-date version of Cassiopeia, you can clone it and follow the same directions as above to add its location to your PYTHONPATH.
