Python Reinforcement Learning using OpenAI Gymnasium – Full Course
By freeCodeCamp.org
Published: Mar 21, 2023“
Learn the basics of reinforcement learning and how to implement it using Gymnasium (previously called OpenAI Gym). Gymnasium is an open source Python library originally created by OpenAI that provides a collection of pre-built environments for reinforcement learning agents. It provides a standard API to communicate between learning algorithms and environments, as well as a standard set of environments compliant with that API.
Reinforcement learning is an area of machine learning concerned with how intelligent agents ought to take actions in an environment in order to maximize the notion of cumulative reward.

Master the HTTP networking protocol by completing over 80 coding exercises and quizzes in JavaScript. Once you’ve learned it all, we’ll build a real web crawler using Node.js to put all the concepts into practice.
HTTP is the backbone of the modern web, and in this course we’ll do a deep dive into all of the fundamentals you’ll need to know to master web networking. We’ll use the Fetch API to interact with a live RESTful server in order to connect the different components of a video game.
