Written by three prominent members of the Perl community who each have several years of experience teaching Perl around the world, this edition has been updated to account for all the recent changes to the language up to Perl 5.8.Perl is the language for people who want to get work done. It started as a tool for Unix system administrators who needed something powerful for small tasks. Since then, Perl has blossomed into a full-featured programming language used for web programming, database manipulation, XML processing, and system administration--on practically all platforms--while remaining the favorite tool for the small daily tasks it was designed for. You might start using Perl because you need it, but you'll continue to use it because you love it.Informed by their years of success at teaching Perl as consultants, the authors have re-engineered the Llama to better match the pace and scope appropriate for readers getting started with Perl, while retaining the detailed discussion, thorough examples, and eclectic wit for which the Llama is famous.The book includes new exercises and solutions so you can practice what you've learned while it's still fresh in your mind. Here are just some of the topics covered:Perl variable typessubroutinesfile operationsregular expressionstext processingstrings and sortingprocess managementusing third party modulesIf you ask Perl programmers today what book they relied on most when they were learning Perl, you'll find that an overwhelming majority will point to the Llama. With good reason. Other books may teach you to program in Perl, but this book will turn you into a Perl programmer.

    With this hands-on guide, you'll learn how to write effective, idiomatic Python code by leveraging its best and possibly most neglected features. Author Luciano Ramalho takes you through Python's core language features and libraries, and shows you how to make your code shorter, faster, and more readable at the same time.Many experienced programmers try to bend Python to fit patterns they learned from other languages, and never discover Python features outside of their experience. With this book, those Python programmers will thoroughly learn how to become proficient in Python 3.This book covers:Python data model: understand how special methods are the key to the consistent behavior of objectsData structures: take full advantage of built-in types, and understand the text vs bytes duality in the Unicode ageFunctions as objects: view Python functions as first-class objects, and understand how this affects popular design patternsObject-oriented idioms: build classes by learning about references, mutability, interfaces, operator overloading, and multiple inheritanceControl flow: leverage context managers, generators, coroutines, and concurrency with the concurrent.futures and asyncio packagesMetaprogramming: understand how properties, attribute descriptors, class decorators, and metaclasses work"

    Many of today’s jobs require that you be familiar with Microsoft Excel. How can you become proficient at Excel when companies aren’t willing to teach you this valuable skill? This leaves many people trying to learn as they go and never quite feeling 100% comfortable with the program. What’s worse, most people haven’t even scratched the surface of Excel’s potential, even if they’ve been using it for years. If you feel this way, you’re not alone. Think about this for a second; what will your career look like in a year if you don’t take action today and improve your Excel skills? How about five years from now? Unless you take matters into your own hands things may not look much different. According to a recent Wall Street Journal article, people who show proficiency in Microsoft Excel and other common office applications earn, on average, 13% more than those who don’t. For most people this could mean tens of thousands of dollars over just a few years, and this doesn’t even factor in lost promotions and job offers. Can you afford to leave so much on the table as a result of maintaining the status quo? I’ve experienced this transformation in my career and can tell you first hand how it has helped me. When I was fresh out of college and working my first accounting job my manager asked me to complete a project that involved using VLOOKUPS. I enthusiastically obliged, walked back to my desk, and proceeded to panic. I tricked myself into thinking that I was an excel expert only because I knew a few formulas, my limited knowledge only scratched the surface. I turned to a college buddy for help; Google. I eventually managed to learn what I needed, after a lot of time and energy. I’ve climbed the ladder and worn many hats since then. I can’t say that the opportunities I’ve earned in my career are solely due to my increasing Excel proficiency. What I can definitely say is that Excel has earned me more opportunities to prove myself to management than waiting for opportunities to materialize on their own. That’s why I decided to write this book. My goal is to take you from Excel novice to master in the shortest time possible. I wrote my book specifically for the busy professional, in an easy to read manner that gets straight to the point and teaches the meat of Excel. I wrote this book for you. Don’t take my word for it: "I think the writing style is helpful for readers to engage. I like that as I read the book, I felt as if I was in front of someone who was actually teaching me. I also liked the fact that the book is written in a laid back manner. I mean Excel is difficult as it is, why would you want to make it worst by adding some weird terminology to the book? Its plain, simple and easy to follow." -Eliana Pereira, Accountant I have helped many people improve their careers through Excel and now it’s your turn. Here is what you get when you download my book: -18 chapters of the most useful Excel techniques that will immediately take your skills to the next level -Practical use cases plus downloadable workbooks so that you can take what you learn and feel, first hand, how to apply those skills to real world scenarios -A FREE copy of my latest book on Google Sheets so you can stay ahead of the curve You’re at the point of decision.
