OpenAI Gym is a toolkit for developing and comparing reinforcement learning algorithms. This is the gym open-source library, which gives you access to an ever-growing variety of environments. You can use it from Python code, and soon from other languages. If you're not sure where to start, we recommend beginning with the docs on our site. There are two basic concepts in reinforcement learning: the environment (namely, the outside world) and the agent (namely, the algorithm you are writing).
