Python 3 Standard Library by Example by Doug Hellmann
Master the Powerful Python 3 Standard Library through Real Code Examples
Introduction
"Distributed with every copy of Python, the Python standard library contains hundreds of Python modules that provide Python tools for interacting with the operating system, Python interpreter, and Python Internet — all of them tested and ready to be used to jump-start the Python development of your Python applications. This book presents selected Python examples demonstrating how to use the most commonly used Python features of the Python modules that support Python’s “batteries included” slogan, taken from the popular Python Module of the Week (PyMOTW) blog series."
“The genius of Doug’s approach is that with 15 minutes per week, any motivated programmer can learn the Python Standard Library. Doug’s guided tour will help you flip the switch to fully power-up Python’s batteries.”
–Raymond Hettinger, Distinguished Python Core Developer
The Python 3 Standard Library contains hundreds of Python modules for interacting with the operating system, interpreter, and Internet – all extensively tested and ready to jump-start application development. Now, Python expert Doug Hellmann introduces every major area of the Python 3.x library through concise source code and output examples. Hellmann’s examples fully demonstrate each feature and are designed for easy learning and reuse.
You’ll find practical code for working with text, data structures, algorithms, dates/times, math, the file system, persistence, data exchange, compression, archiving, crypto, processes/threads, networking, Internet capabilities, email, developer and language tools, the runtime, packages, and more. Each section fully covers one module, with links to additional resources, making this book an ideal tutorial and reference.
The Python 3 Standard Library by Example introduces Python 3.x’s new libraries, significant functionality changes, and new layout and naming conventions. Hellmann also provides expert porting guidance for moving code from 2.x Python standard library modules to their Python 3.x equivalents.
* Manipulate text with string, textwrap, re (regular expressions), and difflib
* Use data structures: enum, collections, array, heapq, queue, struct, copy, and more
* Implement algorithms elegantly and concisely with functools, itertools, and contextlib
* Handle dates/times and advanced mathematical tasks
* Archive and data compression
* Understand data exchange and persistence, including json, dbm, and sqlite
* Sign and verify messages cryptographically
* Manage concurrent operations with processes and threads
* Test, debug, compile, profile, language, import, and package tools
* Control interaction at runtime with interpreters or the environment
About the Author
Doug Hellmann is currently employed by Red Hat to work on OpenStack. He is on the OpenStack Technical Committee and contributes to many aspects of the project. He has been programming in Python since version 1.4, and has worked on a variety of UNIX and non-UNIX platforms for projects in fields such as mapping, medical news publishing, banking, and data center automation. Doug is a Fellow of the Python Software Foundation and served as its Communications Director from 2010-2012. After a year as a regular columnist for Python Magazine, he served as Editor-in-Chief from 2008-2009. Between 2007 and 2011, Doug published the popular "Python Module of the Week" series on his blog, and an earlier version of this book (for Python 2), The Python Standard Library By Example (Addison-Wesley, 2011) . He lives in Athens, Georgia.

This Book’s Target Audience
The audience for this book consists of intermediate-level Python programmers. Thus, although all of the source code is presented with discussion, only a few cases include line-by-line explanations. Every section focuses on the features of the modules, illustrated by the source code and output from fully independent example programs. Each feature is presented as concisely as possible, so the reader can focus on the module or function being demonstrated without being distracted by the supporting code.
An experienced programmer who is familiar with other languages may be able to learn Python from this book, but the text is not intended to be an introduction to the language. Some prior experience writing Python programs will be useful when studying the examples.
Several sections, such as the description of network programming with sockets or hmac encryption, require domain-specific knowledge. The basic information needed to explain the examples is included here, but the range of topics covered by the modules in the standard library makes it impossible to cover every topic comprehensively in a single volume. The discussion of each module is followed by a list of suggested sources for more information and further reading, including online resources, RFC standards documents, and related books."

How This Book Is Organized
"This book supplements the comprehensive reference guide (available at http://docs.python.org), providing fully functional example programs to demonstrate the features described there. The modules are grouped into chapters to make it easy to find an individual module for reference and browse by subject for more leisurely exploration. In the unlikely event that you want to read it through from cover to cover, it is organized to minimize “forward references” to modules not yet covered, although it was not possible to eliminate them entirely."

Acknowledgments
"This book would not have come into being without the contributions and support of many other people.
I was first introduced to Python around 1997 by Dick Wall, while we were working together on GIS software at ERDAS. I remember being simultaneously happy that I had found a new tool language that was so easy to use, and sad that the company did not let us use it for “real work.” I have used Python extensively at all of my subsequent jobs, and I have Dick to thank for the many happy hours I have spent working on software since then.
The Python core development team has created a robust ecosystem of language, tools, and libraries that continue to grow in popularity and find new application areas. Without the continued investment in time and resources they have given us, we would all still be spending our energy reinventing wheel after wheel.
The material in this book started out as a series of blog posts. Without the exceptionally positive response of the readers of the blog, those articles would never have been updated to work with Python 3, and this new book would not exist. Each of those posts has been reviewed and commented on by members of the Python community, with corrections, suggestions, and questions that led to the refinements and improvements that appear in this book. Thank you all for reading along week after week, and contributing your time and attention.
The technical reviewers for the book—Diana Clarke, Ian Cordasco, Mark McClain, Paul McLanahan, and Ryan Petrello—spent many hours looking for issues with the example code and accompanying explanations. Thanks to their diligence, the resulting text is stronger than I could have produced on my own.
Jim Baker provided helpful insight when documenting the readline module, especially by pointing out the gnureadline package for platforms where GNU libraries are old or not installed by default.
Patrick Kettner helped to collect the output for the platform module examples on Windows.
A special thanks goes to the editors, production staff, and marketing team at Addison-Wesley for all of their hard work and assistance in helping me realize my vision for this book and make it a success.
Finally, I want to thank my wife, Theresa Flynn, who has gracefully accepted all of the lost nights and weekends over the course of this new project. Thank you for your advice, encouragement, and support."
