Hands-On Reactive Programming with Python

Introduction to ReactiveX and RxPY

ReactiveX is a library which aims to make asynchronous programming easy. As the header of the project's website says, it is: The Observer pattern done right. ReactiveX is a library based on the idea of observable streams. A stream is an entity that emits zero, one, or several items, over a period of time. This stream of items can be observed by other entities that are interested in receiving these items and manipulated by them. This simple idea is the basis of what has become an incredibly successful way of doing asynchronous programming.

As said in the very first paragraph of this book, asynchronous programming is a very active field. ReactiveX is a typical example of technologies that did not exist a few ...
