- How do you create an observable that emits only one value?
- How do you create an observable that emits one item from each line of a text file?
- Does the just operator return a cold or a hot observable?
- What operator can you use to convert a cold observable to a hot observable and to start to emit items when a first observer subscribes to it?
- Why is it important that observers handle errors?
- How can you convert an observable error to an observable item?
- Why should subscriptions be disposed?

Overview of this book
Reactive programming is central to many concurrent systems, but it’s famous for its steep learning curve, which makes most developers feel like they're hitting a wall. With this book, you will get to grips with reactive programming by steadily exploring various concepts
This hands-on guide gets you started with Reactive Programming (RP) in Python. You will learn abouta the principles and benefits of using RP, which can be leveraged to build powerful concurrent applications. As you progress through the chapters, you will be introduced to the paradigm of Functional and Reactive Programming (FaRP), observables and observers, and concurrency and parallelism. The book will then take you through the implementation of an audio transcoding server and introduce you to a library that helps in the writing of FaRP code. You will understand how to use third-party services and dynamically reconfigure an application.
By the end of the book, you will also have learned how to deploy and scale your applications with Docker and Traefik and explore the significant potential behind the reactive streams concept, and you'll have got to grips with a comprehensive set of best practices.
