Welcome to Python ! I’ve been working with Python for about ten years now, and every new version has caused me to fall in love with the language all over again. Version is no different. If you are new to Python, rest easy — I’ll guide you every step of the way. If, on the other hand, you are an old Python hand exploring the new version, the book is structured so that you can learn the new information you need, without wasting time on already-known information. I wanted to write this book because I love Python. I love it! And I want to share.
