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

    A cold-eyed killer who drank nothing stronger than weak tea, he fought with his bare hands, a sharpened shovel and piano wire. He was a larrikin who went by the book, unless the book was wrong. He set his own bar high and expected others to do the same.Stone Cold is the extraordinary story of one of Australia's most fearless fighters. It takes us into the jungles of New Guinea and Borneo and some of the fiercest battles of World War II. It goes to the cold heart of Korea, where Len emerged from the ranks to excel in the epic Battle of Kapyong and play a key role at the Battle of Maryang San. And it drops us into the centre of the American counterinsurgency war in Vietnam with Len's involvement in the CIA's shadowy black ops program, Phoenix.Action-packed and surprising, Stone Cold gives rich life to a warrior soldier and one of Australia's greatest diggers.

    Sgt. Charles Black is a 35 year veteran of the Iowa State Patrol during those years he has had many experiences and he shares his favorites in this book. In 35 years I have seen a lot of changes from the name of the organization to the primary function. From hearses to ambulances to rescue units with EMT's. From paper list of stolen cars to computers.From no recorders to body cameras. From fist fights to gun fights.But human nature and the effects of drugs and alcohol remain the same.

    ‘Hollywood: Did You Know?’ is a collection of tidbits of information about the content or making of around 400 movies, ranging from the earliest days of the silent era to the present time. I have utilised anecdotes and comments from scores of biographies (authorised and unauthorised), as well as Internet sources, magazine articles, interviews and TV appearances. If, like me, you are fascinated by the world of movies, particularly the days of the studio system, I think you shall find more than enough items here to satisfy your curiosity. I am currently researching a second volume along similar lines. For elderly readers I should point out that there is a considerable amount of ‘bad language’ herein, simply because I quote actors and actresses verbatim. For many of them (even the so-called ‘greats’), peppering their reminiscences with expletives is commonplace. I make no apology for this, however, for I think it is important to present these individuals as they really were, minus the studio hype that tended to elevate them to the status of flawless gods and godesses. Very few lived up to their glowing reputations, I’m afraid. Having said that, I believe that the temptations ever present for these men and women who were suddenly faced with enormous wealth and universal adoration, would test the resolve of most of us, saints and all. And saints have always been few and far between in Tinsel Town. When I published my first book (Hollywood Warts ‘n’ All Volume 1) in 2005, I was accused of ‘muck-raking’, of tarnishing the reputations of deceased stars who could no longer defend themselves. I still get the occasional brickbat along those lines even today, but times have changed. Over the past 20 years or so, hundreds of books have been published about the ‘good old days’ of the studio system; not only stars’ biographies, but accounts from a diverse range of previously unheard from sources. Maids, bodyguards, chauffeurs, secretaries, bell-hops, agents, family members and acquaintances of the rich and famous etc, now put their memories into print, confirming much of what I have been writing about for almost a decade and a half. Of course, there are still those who rail against anyone who deigns to question the ‘snow-jobs’ churned out by studio publicity departments down the decades; the standard complaint being the usual one – the dead cannot defend themselves. Well, there have been more books written about Napoleon Bonaparte and Hitler than most anyone else, yet no-one complains of either man being unable to defend himself. So, again I make no apolgies for anything included in this publication, unless the reader comes across an unforseen error I may have accidentally overlooked, in which case I apologise unreservedly.

    Along the way, we encounter black holes, turtles, snakes, dragons, axe-sharpening, and yak-shaving—and take a guided tour through the theories and methods, both brilliant and misguided, that litter the history of software development, from the famous ‘mythical man-month’ to Extreme Programming. Not just for technophiles but for anyone captivated by the drama of invention, Dreaming in Code offers a window into both the information age and the workings of the human mind.

    And they did it without fanfare or recognition from their employer. Hiltzik's Dealers of Lightning provides a fascinating look at technohistory that sets the record straight. In Dealers of Lightning, Hiltzik describes the forces and faces behind the revolution that the Xerox PARC team single-handedly spawned. The Xerox PARC group was composed solely of top technical minds. The decision was made at Xerox headquarters to give the team complete freedom from deadlines and directives, in hopes of fostering a true creative environment. It worked — perhaps too well. The team responded with a steady output of amazing technology, including the first version of the Internet, the first personal computer, user-friendly word-processing programs, and pop-up menus. Xerox, far from ready for the explosion of innovation, failed to utilize the technology dreamed up by the group. Out of all the dazzling inventions born at Xerox PARC, only a handful were developed and marketed by Xerox. However, one of these inventions, the laser printer, proved successful enough to earn billions for the company, therefore justifying its investment in the research center. Most oftheteam's creations would go on to be developed and perfected by other companies, such as IBM, Apple, and Microsoft. Drawing from interviews with the engineers, executives, and scientists involved in the Xerox PARC, Dealers of Lightning chronicles an amazing era of egos, ideas, and inventions at the dawn of the computer age.
