Welcome to the world of network programming with Python. Python is afull-featured object-oriented programming language with a standard library that includes everything needed to rapidly build powerful network applications. In addition, it has a multitude of third-party libraries and packages that extend Python to every sphere of network programming. Combined with the fun of using Python, with this book, we hope to get you started on your journey so that you master these tools and produce some great networking code.In this book, we are squarely targeting Python 3. Although Python 3 is still establishing itself as the successor to Python 2, version 3 is the future of the language, and we want to demonstrate that it is ready for network programming prime time.It offers many improvements over the previous version, many of which improve the network programming experience, with enhanced standard library modules and new additions.We hope you enjoy this introduction to network programming with Python.This book is aimed at Python 3. While many of the examples will work in Python 2, you'll get the best experience working through this book with a recent version of Python 3. At the time of writing, the latest version is 3.4.3, and the examples were tested against this.
