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.

    The man or woman who works eighteen-hour days and eats his or her meals on the run between appointments is usually viewed with a combination of respect and awe. But for many, this lifestyle leads to family problems, a decline in work productivity, and ultimately to physical and mental collapse.Chained to the Desk, best-selling author and widely respected family therapist Bryan E. Robinson's groundbreaking book, originally published in 1998, was the first comprehensive portrait of the workaholic. Thousands benefited from this innovative book, which profiles the myths behind this greatly misunderstood disorder and the inner psychological battle that work addicts wage against themselves. Intended for anyone touched by what Robinson calls "the best-dressed problem of the twenty-first century," the author also provides an inside look into the impact on those who live and work with them --partners, spouses, children, and colleagues--as well as the appropriate techniques for clinicians who treat them.In this new and updated edition, Robinson portrays the many different kinds of workaholism, drawing on hundreds of case reports from his own original research and years of clinical practice. From California to the Carolinas, men and women tell of their agonizing bouts with workaholism and the devastations left in its wake, struggles made all the more challenging in a world where the computer, cell phone, and Blackberry allow twenty-four-hour access to the office, even on weekends and from vacation spots. Adult children of workaholics describe their childhood pain and the lifelong legacies they still carry, and the spouses or partners of workaholics reveal the isolation and loneliness of their vacant relationships. Employers and business colleagues discuss the cost to the company when workaholism dominates the workplace.Chained to the Desk both counsels and consoles. It provides a step-by-step guide to help readers spot workaholism, understand it, and recover. Robinson presents strategies for workaholics and their loved ones on how to cope, and for people in the workplace on how to distinguish between work efficiency and workaholism.

    This book is neither a step-by-step tutorial nor a reference book. Instead, our goal is to bring a diverse set of software engineering topics together into a single narrative, help readers understand the most important ideas through concrete examples and a learn-by-doing approach, and teach readers enough about each topic to get them started in the field. Courseware for doing the work in the book is available as a virtual machine image that can be downloaded or deployed in the cloud. A free MOOC (massively open online course) at saas-class.org follows the book's content and adds programming assignments and quizzes. See http://saasbook.info for details.

    If you're working with a relational database--whether you're writing applications, performing administrative tasks, or generating reports--you need to know how to interact with your data. Even if you are using a tool that generates SQL for you, such as a reporting tool, there may still be cases where you need to bypass the automatic generation feature and write your own SQL statements.To help you attain this fundamental SQL knowledge, look to "Learning SQL," an introductory guide to SQL, designed primarily for developers just cutting their teeth on the language."Learning SQL" moves you quickly through the basics and then on to some of the more commonly used advanced features. Among the topics discussed: The history of the computerized databaseSQL Data Statements--those used to create, manipulate, and retrieve data stored in your database; example statements include select, update, insert, and deleteSQL Schema Statements--those used to create database objects, such as tables, indexes, and constraintsHow data sets can interact with queriesThe importance of subqueriesData conversion and manipulation via SQL's built-in functionsHow conditional logic can be used in Data StatementsBest of all, "Learning SQL" talks to you in a real-world manner, discussing various platform differences that you're likely to encounter and offering a series of chapter exercises that walk you through the learning process. Whenever possible, the book sticks to the features included in the ANSI SQL standards. This means you'll be able to apply what you learn to any of several different databases; the book covers MySQL, Microsoft SQL Server, and Oracle Database, but the features and syntax should apply just as well (perhaps with some tweaking) to IBM DB2, Sybase Adaptive Server, and PostgreSQL.Put the power and flexibility of SQL to work. With "Learning SQL" you can master this important skill and know that the SQL statements you write are indeed correct.
