Eckel B. Python 3 patterns, recipes, and idioms

Release 1.0. — 2018.This book is aimed at more experienced Python programmers who are looking to deepen their understanding of the language and modern programming idioms. Much of the material focuses on some of the more advanced techniques used by libraries, frameworks, and applications.
Through applying essential software engineering design patterns to Python, Python code becomes even more efficient and reusable from project to project.
The recipes take a problem-solution approach to resolve issues commonly faced by Python programmers across the globe. You will be armed with the knowledge of creating applications with flexible logging, powerful configuration, and command-line options, automated unit tests, and good documentation.The goal of the book:
Develop succinct, expressive programs in Python
Learn the best practices and common idioms through carefully explained and structured recipes
Discover new ways to apply Python for the new age of developmentI have the following motives for creating this book:
Learn more about Python and contribute to the Python community, to help create more and better Python programmers.
Develop more Python consulting and training clients through the publicity generated by the book (see here).
Experiment with group creation of teaching materials for the book, which will benefit me in my own training (see the previous point) but will also benefit anyone choosing to use the book as a text in a course or training seminar. (See Teaching Support).
Generate profits by selling printed books. (But see above about the ability to print the book yourself).
Help raise money for non-U.S. Python user groups via translations, from which I might gain a small percentage.Although there is an introduction for programmers, this book is not intended to be introductory. There are already lots of good introductory books out there.
