About this video

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.

All the code and supporting files for this course are available on GitHub at

Style and Approach

In this video, you'll learn how to build reactive applications in a step-by-step manner. You'll build applications that use reactive programming principles, the Qt GUI framework, and the Tornado web framework. you'll test these parts and then put them together to build a real-time stock exchange.
