Doug Hellmann is currently a senior developer with Racemi, Inc., and communications director of the Python Software Foundation. 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. After a year as a regular columnist for Python Magazine, he served as editor-in-chief from 2008-2009. Since 2007, Doug has published the popular "Python Module of the Week" series on his blog. He lives in Athens, Georgia.
“Hellmann’s writing has become an indispensable resource for me and many others as it fills a critical gap in Python Documentation with examples.”
— Jesse Noller, Python Core Developer and PSF Board Member
Master the Powerful Python Standard Library through Real Code Examples
The Python Standard Library contains hundreds of modules for interacting with the operating system, interpreter, and Internet—all extensively tested and ready to jump-start your application development. The Python Standard Library by Example introduces virtually every important area of the Python 2.7 library through concise, stand-alone source code/output examples, designed for easy learning and reuse.
Building on his popular Python Module of the Week blog series, author and Python expert Doug Hellmann focuses on “showing” not “telling.” He explains code behavior through downloadable examples that fully demonstrate each feature.
You’ll find practical code for working with text, data types, algorithms, math, file systems, networking, the Internet, XML, email, cryptography, concurrency, runtime and language services, and much more. Each section fully covers one module, and links to valuable additional resources, making this book an ideal tutorial and reference. Coverage includes
- Manipulating text with string, textwrap, re, and difflib
- Implementing data structures: collections, array, queue, struct, copy, and more
- Reading, writing, and manipulating files and directories
- Regular expression pattern matching
- Exchanging data and providing for persistence Archiving and data compression
- Managing processes and threads
- Using application “building blocks”: parsing command-line options, prompting for passwords, scheduling events, and logging
- Testing, debugging, and compilation
- Controlling runtime configuration
- Using module and package utilities
If you’re new to Python, this book will quickly give you access to a whole new world of functionality. If you’ve worked with Python before, you’ll discover new, powerful solutions and better ways to use the modules you’ve already tried.

A lot of information at a great price; I suggest a hard copy because you'll want to flip through it quickly,
This review is from: The Python Standard Library by Example (Developer's Library) (Paperback)
If you have ever worked with Python, you have probably come across Python Module of the Week (PyMOTW) or virtualenvwrapper. Both are the work of Doug Hellmann. He has now brought to life The Python Standard Library By Example. If Python gives you the batteries, Hellmann gives you not only an instruction manual but the "on" switch to get you going right away.The Python documentation is really great, but might leave some with a "some assembly required" feeling. The book's examples aim to be more complete, while still covering a serious breadth of the Standard Library. Do not expect to use all of the examples in your project without some modification, customization and expansion. After all, they are miniature projects in their own right. By the Numbers: It weighs in at a whopping 1300-something pages across 19 chapters. This translates roughly to a 2-inch print copy, or a 7.3 MB PDF. The accompanying source is 5.5 MB after unzipping and contains 113... Read more

This review is from: The Python Standard Library by Example (Developer's Library) (Paperback)
I had pre-ordered this book, as the author's website and blogs have always been excellent in their ability to give concise examples for the usage of Python's extensive standard library. I have now had the book for a few days and I am very pleased with it.I sometimes wonder when I will buy my last physical book, as digital versions are becoming standard. This book, however, is a great example of some of the great computer books that lived most of their lives right next to my computer: a well-organized reference manual with a great index and table of contents (you can view these on the Amazon page for this title). I teach Python in my high school Computer Science classes, and have always loved the fact that I can write Python code quickly and successfully for so many tasks that come up when teaching. Learning Python is one thing--being able to utilize the standard library in "Pythonic" ways is another skill entirely. The core language is perfect for... Read more

useful contribution to python literature, By Michael Deacon (Berkeley, CA, USA) - See all my reviews
This review is from: The Python Standard Library by Example (Developer's Library) (Paperback)
While most python books teach you how to write code in the language, this book takes a different approach - it shows you how to build python programs using existing code from the standard library. As every python programmer knows, the best way to leverage the power of the language is to use the built-in functionality of the library.True to its title, the book features numerous examples, each one fully annotated, explaining how to use the modules. Need to parse text using regular expressions? Python has a module for that. What about searching file system directories recursively? Network sockets? Those and hundreds of other useful tools are available in the standard library. Hellman shows you how to use the existing modules in the library so that you don't have to reinvent the wheel. A word of caution for those who are new to python: the book assumes familiarity with basic language syntax. Overall, this book compares favorably with the other... Read more |
