Content Introduction

This book is the authoritative Python Language Reference guide that covers the most important parts of the core Python language and the Python library. The book contains some high-level topics that are not included in official Python documents or other materials, and are concise and readable.

This edition is fully updated on the content, introducing the new programming language features and library modules introduced in Python 2.6 and Python 3, as well as analyzing the challenges that Python programmers face: whether to continue using existing Python code or plan to port it to Python
3?

Author Introduction

David M. Beazley began to use Python programming as early as 1996. While working at the Los Alamos National Laboratory, he taught many volunteers to write scientific computing software in Python. The Dabeaz he founded
The company provides software development, training and consulting services, specialising in the practical application of Python, Ruby, Perl and other dynamic programming languages. He is a member of the Python Software Foundation.
