To get the most out of this book

In this book, reinforcement learning algorithms are implemented in Python. To reproduce the many examples in this book, you need to possess a good knowledge of the Python environment. We have used Python 3.6 and above to build various applications. In that spirit, we have tried to keep all of the code as friendly and readable as possible. We feel that this will enable you to easily understand the code and readily use it in different scenarios.
