Book SynopsisBrett Slatkin is a principal software engineer at Google. He is the technical co-founder of Google Surveys, the co-creator of the PubSubHubbub protocol, and he launched Google's first cloud computing product (App Engine). Fourteen years ago, he cut his teeth using Python to manage Google's enormous fleet of servers. Outside of his day job, he likes to play piano and surf (both poorly). He also enjoys writing about programming-related topics on his personal website (https://onebigfluke.com). He earned his B.S. in computer engineering from Columbia University in the City of New York. He lives in San Francisco.Trade Review“I have been recommending this book enthusiastically since the first edition appeared in 2015. This new edition, updated and expanded for Python 3, is a treasure trove of practical Python programming wisdom that can benefit programmers of all experience levels.” –Wes McKinney, Creator of Python Pandas project, Director of Ursa Labs “If you’re coming from another language, this is your definitive guide to taking full advantage of the unique features Python has to offer. I’ve been working with Python for nearly twenty years and I still learned a bunch of useful tricks, especially around newer features introduced by Python 3. Effective Python is crammed with actionable advice, and really helps define what our community means when they talk about Pythonic code.” –Simon Willison, Co-creator of Django “I’ve been programming in Python for years and thought I knew it pretty well. Thanks to this treasure trove of tips and techniques, I’ve discovered many ways to improve my Python code to make it faster (e.g., using bisect to search sorted lists), easier to read (e.g., enforcing keyword-only arguments), less prone to error (e.g., unpacking with starred expressions), and more Pythonic (e.g., using zip to iterate over lists in parallel). Plus, the second edition is a great way to quickly get up to speed on Python 3 features, such as the walrus operator, f-strings, and the typing module.” –Pamela Fox, Creator of Khan Academy programming courses “Now that Python 3 has finally become the standard version of Python, it’s already gone through eight minor releases and a lot of new features have been added throughout. Brett Slatkin returns with a second edition of Effective Python with a huge new list of Python idioms and straightforward recommendations, catching up with everything that’s introduced in version 3 all the way through 3.8 that we’ll all want to use as we finally leave Python 2 behind. Early sections lay out an enormous list of tips regarding new Python 3 syntaxes and concepts like string and byte objects, f-strings, assignment expressions (and their special nickname you might not know), and catch-all unpacking of tuples. Later sections take on bigger subjects, all of which are packed with things I either didn’t know or which I’m always trying to teach to others, including ‘Metaclasses and Attributes’ (good advice includes ‘Prefer Class Decorators over Metaclasses’ and also introduces a new magic method ‘__init_subclass__()’ I wasn’t familiar with), ‘Concurrency’ (favorite advice: ‘Use Threads for Blocking I/O, but not Parallelism,’ but it also covers asyncio and coroutines correctly) and ‘Robustness and Performance’ (advice given: ‘Profile before Optimizing’). It’s a joy to go through each section as everything I read is terrific best practice information smartly stated, and I’m considering quoting from this book in the future as it has such great advice all throughout. This is the definite winner for the ‘if you only read one Python book this year...’ contest.” –Mike Bayer, Creator of SQLAlchemy “This is a great book for both novice and experienced programmers. The code examples and explanations are well thought out and explained concisely and thoroughly. The second edition updates the advice for Python 3, and it’s fantastic! I’ve been using Python for almost 20 years, and I learned something new every few pages. The advice given in this book will serve anyone well.” –Titus Brown, Associate Professor at UC Davis “Once again, Brett Slatkin has managed to condense a wide range of solid practices from the community into a single volume. From exotic topics like metaclasses and concurrency to crucial basics like robustness, testing, and collaboration, the updated Effective Python makes a consensus view of what’s ‘Pythonic’ available to a wide audience.” –Brandon Rhodes, Author of python-patterns.guideTable of ContentsPrefaceChapter 1 Pythonic ThinkingChapter 2 Lists and DictionariesChapter 3 FunctionsChapter 4 Comprehensions and GeneratorsChapter 5 Classes and InterfacesChapter 6 Metaclasses and AttributesChapter 7 Concurrency and ParallelismChapter 8 Robustness and PerformanceChapter 9 Testing and DebuggingChapter 10 CollaborationIndex

Book SynopsisMichael Hartl created the legendary Ruby on Rails Tutorial that helped jumpstart thousands of web development careers. A cofounder and principal author at Learn Enough, Hartl previously earned a Ph.D. in physics at the California Institute of Technology (Caltech), where he received a Lifetime Achievement Award for Excellence in Teaching. He is also an alumnus of Harvard University and the world-renowned Y Combinator entrepreneur program.Trade ReviewPraise for Michael Hartl's Books and Videos on Ruby on Rails "My former company (CD Baby) was one of the first to loudly switch to Ruby on Rails, and then even more loudly switch back to PHP. (Google me to read about the drama.) This book by Michael Hartl came so highly recommended that I had to try it, and the Ruby on RailsTM Tutorial is what I used to switch back to Rails again."--From the Foreword by Derek Sivers (sivers.org)Formerly: founder of CD Baby; Currently: founder of Thoughts Ltd. "I started working on a project but didn't quite understand some rails concepts. Needed a good tutorial and found lots of recommendations for @mhartl's rails tutorial . . . and man it's so good. The hype def matches the product."--Pratik Tamang, https://twitter.com/codingkrazy "The rails tutorial by @mhartl is the best web dev resource ever written."--Daniel Gamboa, Product Manager, Figment "My first programming book was the Ruby on Rails Tutorial from @mhartl. The best part was it taught me general skills to be an effective developer."--Jack Gray, staknine.com "Michael Hartl's Rails Tutorial book is the #1 (and only, in my opinion) place to start when it comes to books about learning Rails. . . . It's an amazing piece of work and, unusually, walks you through building a Rails app from start to finish with testing. If you want to read just one book and feel like a Rails master by the end of it, pick the Ruby on RailsTM Tutorial."--Peter Cooper, editor, Ruby Inside "Michael Hartl's Ruby on RailsTM Tutorial seamlessly taught me about not only Ruby on Rails, but also the underlying Ruby language, HTML, CSS, a bit of JavaScript, and even some SQL--but most importantly it showed me how to build a web application (Twitter) in a short amount of time."--Mattan Griffel, cofounder & CEO of One Month "Although I'm a Python/Django developer by trade, I can't stress enough how much this book has helped me. As an undergraduate, completely detached from industry, this book showed me how to use version control, how to write tests, and, most importantly--despite the steep learning curve for setting up and getting stuff running--how the end result of perseverance is extremely gratifying. It made me fall in love with technology all over again. This is the book I direct all my friends to who want to start learning programming/building stuff. Thank you, Michael!"--Prakhar Srivastav, software engineer, Xcite.com, Kuwait "It has to be the best-written book of its type I've ever seen, and I can't recommend it enough."--Daniel Hollands, administrator of Birmingham.IO "For those wanting to learn Ruby on Rails, Hartl's Ruby on RailsTM Tutorial is (in my opinion) the best way to do it."--David Young, software developer and author at deepinthecode.com "This is a great tutorial for a lot of reasons, because aside from just teaching Rails, Hartl is also teaching good development practices."--Michael Denomy, full-stack web developer "Without a doubt, the best way I learned Ruby on Rails was by building an actual working app. I used Michael Hartl's Ruby on RailsTM Tutorial, which showed me how to get a very basic Twitter-like app up and running from scratch. I cannot recommend this tutorial enough; getting something up and going fast was key; it beats memorization by a mile."--James Fend, serial entrepreneur, JamesFend.com "The book gives you the theory and practice, while the videos focus on showing you in person how it's done. Highly recommended combo."--Antonio Cangiano, software engineer, IBM "The author is clearly an expert at the Ruby language and the Rails framework, but more than that, he is a working software engineer who introduces best practices throughout the text."--Gregory Charles, principal software developer at Fairway TechnologiesTable of ContentsForeword xviiPreface xixAcknowledgments xxvAbout the Author xxvii Chapter 1: From Zero to Deploy 11.1 Up and Running 51.2 The First Application 141.3 Version Control with Git 351.4 Deploying 521.5 Conclusion 611.6 Conventions Used in This Book 62 Chapter 2: A Toy App 652.1 Planning the Application 662.2 The Users Resource 712.3 The Microposts Resource 872.4 Conclusion 104 Chapter 3: Mostly Static Pages 1073.1 Sample App Setup 1073.2 Static Pages 1153.3 Getting Started with Testing 1263.4 Slightly Dynamic Pages 1353.5 Conclusion 1523.6 Advanced Testing Setup 153 Chapter 4: Rails-Flavored Ruby 1594.1 Motivation 1594.2 Strings and Methods 1654.3 Other Data Structures 1774.4 Ruby Classes 1924.5 Conclusion 204 Chapter 5: Filling in the Layout 2075.1 Adding Some Structure 2075.2 Sass and the Asset Pipeline 2325.3 Layout Links 2425.4 User Signup: A First Step 2555.5 Conclusion 260 Chapter 6: Modeling Users 2636.1 User Model 2646.2 User Validations 2796.3 Adding a Secure Password 3036.4 Conclusion 313 Chapter 7: Sign Up 3157.1 Showing Users 3167.2 Signup Form 3377.3 Unsuccessful Signups 3467.4 Successful Signups 3617.5 Professional-Grade Deployment 3747.6 Conclusion 380 Chapter 8: Basic Login 3818.1 Sessions 3818.2 Logging In 3988.3 Logging Out 4378.4 Conclusion 443 Chapter 9: Advanced Login 4459.1 Remember Me 4459.2 "Remember Me" Checkbox 4709.3 Remember Tests 4769.4 Conclusion 489 Chapter 10: Updating, Showing, and Deleting Users 49310.1 Updating Users 49310.2 Authorization 50910.3 Showing All Users 52610.4 Deleting Users 54410.5 Conclusion 556 Chapter 11: Account Activation 55911.1 Account Activations Resource 56011.2 Account Activation Emails 56811.3 Activating the Account 58511.4 Email in Production 61011.5 Conclusion 619 Chapter 12: Password Reset 62112.1 Password Resets Resource 62312.2 Password Reset Emails 63412.3 Resetting the Password 64112.4 Email in Production (Take 2) 65812.5 Conclusion 65912.6 Proof of Expiration Comparison 661 Chapter 13: User Microposts 66313.1 A Micropost Model 66313.2 Showing Microposts 67913.3 Manipulating Microposts 69313.4 Micropost Images 72613.5 Conclusion 752 Chapter 14: Following Users 75514.1 The Relationship Model 75614.2 A Web Interface for Following Users 77414.3 The Status Feed 80514.4 Conclusion 821 Index 825

Book SynopsisTake Control of Your Data and Use Python with ConfidenceRequiring no prior programming experience, Managing Your Biological Data with Python empowers biologists and other life scientists to work with biological data on their own using the Python language. The book teaches them not only how to program but also how to manage their data. It shows how to read data from files in different formats, analyze and manipulate the data, and write the results to a file or computer screen. The first part of the text introduces the Python language and teaches readers how to write their first programs. The second part presents the basic elements of the language, enabling readers to write small programs independently. The third part explains how to create bigger programs using techniques to write well-organized, efficient, and error-free code. The fourth part on data visualization shows how to plot data and draw a figure for an article or slide pTrade Review“… a significant step forward … The book is cleverly designed to cover a wide range of subjects in a pleasant, easy-to-follow sequence of chapters. These have been carefully prepared so that the minimum level of interdependence is kept, making it possible to begin working at virtually any level without falling into intricate cross-references. A beginner will find the first chapters quite welcoming while a person with medium or even high levels of programming experience can easily find a suitable entry point in the middle.The book is written using an entertaining style that pushes the reader into a naturally built engaging experience … the authors have chosen a collection of underlying subject areas that cover a very wide variety of interests, ensuring that mixed audiences are kept engaged. In that sense, the content becomes adaptable to the wide diversity of learners that are found in today's communities of specialised biologists.… also usable as a reference guide, due to the richness of its worked examples that will prove valuable as seeds for code development for programmers at any level. … as a single book to support learning Python for problem solvers in the life sciences, this book is certainly a very smart choice. It is also ready for creative teachers to develop more in the same direction.”—Pedro L. Fernandes, Instituto Gulbenkian de Ciência"Having read Managing Your Biological Data with Python brings back memories of the times I started writing my first lines of code nearly a decade ago. As a beginning structural biologist without any coding experience, this book would have been a welcome companion to quickly get me started on my bioinformatical projects with Python. It is this, often pragmatic, attitude scientists have towards programming that makes Python the language of choice for many. A clear syntax, powerful build-in functions and a lively ecosystem of user contributed modules allow you to do advanced things with only little lines of code. The book introduces you to the basic principles of programming in Python using the many build-in functions. It does so using practical examples that you can start using right away in your day-to-day research.Python’s modular design principles could even be seen in the organization of this book. If you have never written a line of code in your life, the first chapters are indispensable to teach you basic coding principles but if you have some experience, you can safely skip these. I would however, recommend to read the ones introducing the build-in functions. It never hurts to refresh your memory on the many powerful build-ins Python actually has; I certainly forgot about one or two of them. Working your way through the first chapters will help you get comfortable with Python and lay the foundation for writing more advanced programs in the remaining chapters. These chapters introduce some of the powerful community contributed Python modules that make your life as a biologist a whole lot easier. Again, the example code introducing these modules is of high practical value and together with the coding recipes in the ‘cookbook’ chapter they provide a solid blueprint for you to build your own code upon. I’m confident that reading Managing Your Biological Data with Python will quickly allow you to get the most out of your data and start answering those trilling scientific questions you have, and do all of that while having fun. "—Marc van Dijk, Structural biologist, bioinformaticien, and eScience entrepreneur, Bijvoet Center for Biomolecular Research, Utrecht University, The Netherlands"For many biologists faced with computational challenges, Python has become the language of choice, due to its power, elegance, and simplicity. Managing Your Biological Data with Python by Allegra Via et al. teaches Python using biological examples and discusses important Python-driven applications, such as PyMol and Biopython. The book is an excellent resource for any biologist needing relevant programming skills."—Thomas Hamelryck, Associate Professor, Bioinformatics Center, University of Copenhagen, Denmark"Biological data volumes are growing rapidly as high-throughput technologies (e.g., DNA microarrays or DNA/RNA sequencing) improve. Managing and analyzing biological data are becoming more demanding and the application of programming techniques has simply become a standard. Managing Your Biological Data with Python is one of very few user-friendly books for biologists. It is amazing how clearly authors explain the possible applications of Python for data management (parsing data records, filtering and sorting data) and data visualization (also using the Python interface to R). The book also offers the description of modular programming, which is simply excellent! It guides readers from writing simple functions through writing classes to building program pipelines—everything according to Python coding standards and in an easy-to-follow way. This is absolutely the best book to start learning Python. Intermediate Python users can use this book to learn some new tricks that they could implement in their own code. I can highly recommend this book to researchers, students, and their lecturers."—Dr. Barbara Uszczynska, Centre de Regulació Genòmica (CRG), Barcelona, SpainTable of ContentsGetting Started: The Python Shell.
