PokerKit
========
PokerKit is an open-source software library, written in pure Python, for simulating games, evaluating hands, and facilitating statistical analysis, developed by the University of Toronto Computer Poker Student Research Group. PokerKit supports an extensive array of poker variants and it provides a flexible architecture for users to define their custom games. These facilities are exposed via an intuitive unified high-level programmatic API. The library can be used in a variety of use cases, from poker AI development, and tool creation, to online poker casino implementation. PokerKit's reliability has been established through static type checking, extensive doctests, and unit tests, achieving 99% code coverage.
Features
--------
* Extensive poker game logic for major and minor poker variants.
* High-speed hand evaluations.
* Customizable game states and parameters.
* Robust implementation with static type checking and extensive unit tests and doctests.
Installation
------------
The PokerKit library requires Python Version 3.11 or above and can be installed using pip:
.. code-block:: bash
pip install pokerkit
Usages
------
