In order to do so, I created three files. The first step is to setup the skeleton of the code such that it works. Small note on the GUI: it did not work for my directly using Python 3. However, the implementation of the bot in this tutorial depends on this choice, so you need to rewrite some if the code if you plan to change the engine (and/or GUI). The choice for the engine (and/or the GUI) is arbitrary and can be replaced by any engine (and/or GUI) you like. If you are interested, you can optionally install the following package ( PyPokerGUI): pip install pypokerguiīoth the engine and the GUI have excellent tutorials on their GitHub pages in how to use them. It also has a GUI available which can graphically display a game. Install the following package ( PyPokerEngine) using pip: pip install PyPokerEngine Step 1 – Setup Python and Install Packagesįirst, we need an engine in which we can simulate our poker bot. In this tutorial, you will learn step-by-step how to implement a poker bot in Python. 4 min read Photo by Pranjall Kumar / Unsplash.Most of the tricky client logic is backed up by tests, which were written using MochaJS. Here it has been extended to calculate the best 5-card hand from any 7-card hand. Poker Evaluator poker-evaluator is used for evaluating the winning hand when it comes time to show down. This route was chosen to avoid uploading 318,505,200 images to the cloud, and allows us to modify the card assets easily. The resulting image is than uploaded to imgur, which gives us a single URL that can be passed as an attachment to the Slack API. It simplifies many of the complex player polling interactions, that would otherwise be Death By Timers, into very legible code.Įach card is a separate image, and board images are created on the fly by pasting several cards onto a single canvas (with the help of lwip). The majority of this client is written using RxJS. NodeJS Slack Client node-slack-client abstracts the basics of a Slack bot, including authentication, getting messages from players, and posting messages or attachments to the channel. This is very helpful when diagnosing a logic bug: This is the same test suite that is run on each pull request. The tests produce legible output that matches what users in Slack would see.
