Book Description

Discover how project Reactor enhances the reactive programming paradigm and allows you to build scalable asynchronous applications Key FeaturesUse reactive APIs, Flux, and Mono to implement reactive extensionsCreate concurrent applications without the complexity of Java's concurrent APIUnderstand techniques to implement event-driven and reactive applicationsBook Description Reactor is an implementation of the Java 9 Reactive Streams specification, an API for asynchronous data processing. This specification is based on a reactive programming paradigm, enabling developers to build enterprise-grade, robust applications with reduced complexity and in less time. Hands-On Reactive Programming with Reactor shows you how Reactor works, as well as how to use it to develop reactive applications in Java. The book begins with the fundamentals of Reactor and the role it plays in building effective applications. You will learn how to build fully non-blocking applications and will later be guided by the Publisher and Subscriber APIs. You will gain an understanding how to use two reactive composable APIs, Flux and Mono, which are used extensively to implement Reactive Extensions. All of these components are combined using various operations to build a complete solution. In addition to this, you will get to grips with the Flow API and understand backpressure in order to control overruns. You will also study the use of Spring WebFlux, an extension of the Reactor framework for building microservices. By the end of the book, you will have gained enough confidence to build reactive and scalable microservices. What you will learnExplore benefits of the Reactive paradigm and the Reactive Streams APIDiscover the impact of Flux and Mono implications in ReactorExpand and repeat data in stream processingGet to grips with various types of processors and choose the best oneUnderstand how to map errors to make corrections easierCreate robust tests using testing utilities offered by ReactorFind the best way to schedule the execution of codeWho this book is for If you’re looking to develop event- and data-driven applications easily with Reactor, this book is for you. Sound knowledge of Java fundamentals is necessary to understand the concepts covered in the book.

Book Description

In 2005, Microsoft quietly announced an initiative to bring dynamic languages to the .NET platform. The starting point for this project was a .NET implementation of Python, dubbed IronPython. After a couple years of incubation, IronPython is ready for real-world use. It blends the simplicity, elegance, and dynamism of Python with the power of the .NET framework. IronPython in Action offers a comprehensive, hands-on introduction to Microsoft's exciting new approach for programming the .NET framework. It approaches IronPython as a first class .NET language, fully integrated with the .NET environment, Visual Studio, and even the open-source Mono implementation. You'll learn how IronPython can be embedded as a ready-made scripting language into C# and VB.NET programs, used for writing full applications or for web development with ASP. Even better, you'll see how IronPython works in Silverlight for client-side web programming. IronPython opens up exciting new possibilities. Because it's a dynamic language, it permits programming paradigms not easily available in VB and C#. In this book, authors Michael Foord and Christian Muirhead explore the world of functional programming, live introspection, dynamic typing and duck typing , metaprogramming, and more. IronPython in Action explores these topics with examples, making use of the Python interactive console to explore the .NET framework with live objects. The expert authors provide a complete introduction for programmers to both the Python language and the power of the .NET framework. The book also shows how to extend IronPython with C#, extending C# and VB.NET applications with Python, using IronPython with .NET 3.0 and Powershell, IronPython as a Windows scripting tool, and much more. Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book.

Book Description

What is the point of learning Python if you're just starting out? What does Python have in store for you, exactly? Python is an object-oriented programming language that is high-level and has built-in data structures and dynamic semantics. It supports various programming paradigms, including structures, object-oriented programming, and functional programming, among others. Python provides several distinct modules and bundles, which enables program modularity and code reuse to be accomplished. This book is based on Mike Kernell's Python in Object-Oriented Programming. On the other hand, this book is not only a translation of those other works into Python. To adapt the material for this book, we have drastically altered the arrangement and substance of the book, as shown in the following diagram: To use the Python capabilities, the code base has been completely rebuilt. In addition, it contains comprehensive Python codes. Each chapter in this book is designed to provide a pedagogical approach that begins with the fundamentals of Python programming and an introduction to object-oriented programming. New and improved examples assist beginners in putting theory into practice. In addition, we include core concepts like operator overloading, encapsulation, and polymorphism. The book's main body covers the most critical object-oriented principles employed in Python. Concluding with a discussion on the game programming projects. Python data structures and procedures, object-oriented programming, and sort algorithms are all taught in detail in this book without the need for you to spend a lot of time learning computer science theory as you would otherwise. If you're new to Python, this book is an excellent location to begin your learning process. Additionally, you'll get hands-on experience with Programming language game development projects throughout this course. When you blend work with play, you will be able to remember more of what you've learned in the long run. The book is a fantastic resource for those new to the topic of study. This book takes you by the hand and walks you through the process of learning to code in Python, covering topics such as: What is Python, and how does it work? Python Data Types Creating Interactive Projects File Handling in Python Gaming Projects in Python Object-Oriented Programming Data Structures Python Data Types ...and much more!! Designed as an ultimate guide, this book will serve as a comprehensive, step-by-step guidebook that will assist you in learning and experiencing Python in a relaxed and steady manner. So, hurry up and get your hands on a copy before they sell out completely!

Book Description

"This video will be your guide to getting started with Reactive programming in Python. You will begin with the general concepts of Reactive programming and then gradually move on to work with asynchronous data streams. You will then be introduced to functional reactive programming and will learn to apply FRP in practical use cases in Python. You will understand how ReactiveX works and how it efficiently supports sequences of data. You will then understand the role of asynchronous programming and event-based programming in detail to build reactive extensions. You will learn to create dataflow-based systems, the building blocks of reactive programming. This course will take you through creating, merging, filtering, transforming, and error-handling observables to extend your asynchronous code. You will then learn to scale applications using multi-node clusters and will learn to unit-test your clusters. This video also introduces you to Reactive microservices with Python."--Resource description page.
