Python 2 and 3 Compatibility

This book explains clean ways to write code that will run on both Python 2 and 3. It is a tutorial oriented book with detailed examples of how to convert existing Python 2-compatible code to code that will run reliably on both Python 2 and 3. Although Python 3 is considered the future of Python, Python 2.x will be maintained for several more years, alongside Python 3 which is not backwards compatible. Developers who need to support both versions will find this book guides them to provide Python 3 compatibility to their existing Python 2 projects. It acts as a manual to convert existing Python 2 code to achieve Python 3 and 2 compatibility.Implementing Python 2.x and 3.x Compatibility explains the syntactical differences between Python 2 and 3, and how to use Python packages Python-Future and Six to implement support. Developers working on either small, medium, or large projects will appreciate the author's clear explanations, detailed examples, and clean techniques to help them extend support for both versions to their existing Python 2-compatible projects.WHAT YOU'LL LEARN: The syntactical differences between Python 2 and 3 How to use the Six and Future Libraries The new features in Python 3 How to decide on what Python versions to support when doing neutral support How to decide on whether to port or provide support for both versions AUDIENCE: The book is for professional Python developers and enthusiasts that want to implement Python 3 support for their existing Python 2 compatible code.
