Python is considered easy to learn, but there's no quicker way to mastery of the language than learning from an expert teacher. This edition of "Learning Python" puts you in the hands of two expert teachers, Mark Lutz and David Ascher, whose friendly, well-structured prose has guided many a programmer to proficiency with the language. "Learning Python," Second Edition, offers programmers a comprehensive learning tool for Python and object-oriented programming. Thoroughly updated for the numerous language and class presentation changes that have taken place since the release of the first edition in 1999, this guide introduces the basic elements of the latest release of Python 2.3 and covers new features, such as list comprehensions, nested scopes, and iterators/generators. Beyond language features, this edition of "Learning Python" also includes new context for less-experienced programmers, including fresh overviews of object-oriented programming and dynamic typing, new discussions of program launch and configuration options, new coverage of documentation sources, and more. There are also new use cases throughout to make the application of language features more concrete. The first part of "Learning Python" gives programmers all the information they'll need to understand and construct programs in the Python language, including types, operators, statements, classes, functions, modules and exceptions. The authors then present more advanced material, showing how Python performs common tasks by offering real applications and the libraries available for those applications. Each chapter ends with a series of exercises that will test your Python skills and measure your understanding."Learning Python," Second Edition is a self-paced book that allows readers to focus on the core Python language in depth. As you work through the book, you'll gain a deep and complete understanding of the Python language that will help you to understand the larger application-level examples that you'll encounter on your own. If you're interested in learning Python--and want to do so quickly and efficiently--then "Learning Python," Second Edition is your best choice.

    Each idiom comes with a detailed description, example code showing the "wrong" way to do it, and code for the idiomatic, "Pythonic" alternative. *This version of the book is for Python 2.7.3+. There is also a Python 3.3+ version available.* "Writing Idiomatic Python" contains the most common and important Python idioms in a format that maximizes identification and understanding. Each idiom is presented as a recommendation to write some commonly used piece of code. It is followed by an explanation of why the idiom is important. It also contains two code samples: the "Harmful" way to write it and the "Idiomatic" way. * The "Harmful" way helps you identify the idiom in your own code. * The "Idiomatic" way shows you how to easily translate that code into idiomatic Python. This book is perfect for you: * If you're coming to Python from another programming language * If you're learning Python as a first programming language * If you're looking to increase the readability, maintainability, and correctness of your Python code What is "Idiomatic" Python? Every programming language has its own idioms. Programming language idioms are nothing more than the generally accepted way of writing a certain piece of code. Consistently writing idiomatic code has a number of important benefits: * Others can read and understand your code easily * Others can maintain and enhance your code with minimal effort * Your code will contain fewer bugs * Your code will teach others to write correct code without any effort on your part

    It will allow you to avoid some likely pitfalls and it will guide you to asking, yourself and your clients, the right questions. Though many people focus on the visualization techniques in Kanban the true value only emerges when you, as a kanban system manager, are apt at noticing the anti-patterns that occur on the kanban board and are able to take appropriate actions. David generously shares his vast experience in this field, with plenty real case scenarios, to the benefit of the reader. After reading this book I toyed with the idea: Would I've changed my approach to coaching my previous clients, in their adoption of agile values and practices, had I read this at the time? Well, I certainly would have, for all of them, and I'm sure it would have meant a smoother change process for the agilely challenged organizations. David provides a comprehensive guide to implementing Kanban in a software development/maintenance environment. Covering the mechanics, dynamics, principles and rationale behind why Kanban is a so promising framework for managing the work of a variety of teams and groups and being an evolutionary-based change management driver. Kanban is the practical approach to implement Lean Software Development, and this book is the practical guide for how to start using Kanban, and how to adapt the system for advanced needs. The book is clear and flowing, even though it covers some quite technical material. I would recommend it to Development managers, Project/Program managers, Agile Coaches/Consultants. It addresses concerns/needs of Novice as well as those already familiar with Kanban and looking for advanced answers. Even if you don't intend to implement a kanban system, there are a lot of techniques and ideas that are easily applicable to any product development/maintenance environment, agile or not. Bottom line, highly recommended.
