The book Python Pocket Reference—a quick-reference resource—has been published in five editions. Each edition has incorporated updates in Python itself, as well its libraries, tools, and common practice. I (or O'Reilly) maintain support pages for each edition of this book. Please select the relevant link in the first column of the table below:
This book is a reference-only but content-rich resource for both Python 3.X and 2.X. It covers the Python language as well as its commonly used libraries and tools, and provides quick reference to formal and complete details not given elsewhere. As such, this book is designed to work as a supplement, companion, and extension to other books—including the language foundations tutorial Learning Python, as well as the follow-up applications tutorial Programming Python. Together, these 3 books provide a 3,500-page set of related Python documentation. For more on this book's scope, see also these content pointers.
