Guide To: Functional Python & Comprehension Constructs

<div><b>Do you want to take your Python to the next level?</b></div><div><b></b></div>Python is easy to learn. You can learn the basics in a day and be<br />productive with it. But there are <b><i>more advanced constructs</i></b> that you<br />will eventually run across if you spend enough time with it. Don't be confused by these. Learn them, embrace them, and improve your code and others.<div><br /><div></div><div><b>Functional Programming and Comprehensions</b></div><div>Functional programming is a somewhat hidden aspect of Python. Though it supports many of the functional constructs, the style is not widely adopted.<br /><br />On the flip side functional programming appears to be making a resurgence, because of the benefits it can provide.</div><div> </div><div></div><div></div><div></div><div></div><div></div><div>Comprehensions are an alternative Pythonic construct for programming in a similar manner.These are features of Python that are commonly used instead of their functional counterparts. This book covers:</div><div><ul><li>List Comprehensions</li><li>Generator Expressions</li><li>Set Comprehensions</li><li>Dict Comprehensions</li></ul><div><br /><div></div><br /><div><b>Write Python code like the masters</b></div><div></div><div>These constructs, while not necessary per se, allow you to be more succinct,<br />re-use code, and think about code in a different way. You will learn:</div><div><ul><li>How the constructs work</li><li>When to use them</li><li>Real life examples from the standard library</li></ul><b>Understand other's code</b><br />This book covers many of these intermediate constructs that are available in Python. <i><b>The book covers both Python 2 and 3.</b></i> Topics include:</div><div><ul><li>Functional programming </li><li>List comprehensions</li><li>Generator expressions</li><li>Set & dict comprehensions </li></ul><b>Based on popular tutorials and sessions</b> </div><div>I have taught material similar to these constructs at popular tutorials at conferences such as PyCon, OSCON and Strata (and other<br />conferences). This book is based on my experience teaching and using<br />Python for many years. I hope you learn something while in the course<br />of your reading. Maybe it will help you in your next task, code<br />review, or job interview.</div></div><div> </div><div></div><div></div><div></div><div></div><div></div><div></div><div><b>Up Your Advanced Python Skills</b></div>It is assumed that the reader has some knowledge of Python. You will walk away knowing the functional constructs, when to use them, how to use them, and when to use their Pythonic counterparts. The functional aspects will aid in grokking Python, Lisps, and other newer languages such as Clojure and Scala.</div>
