Chapter 4. Asynchronous Programming

In this chapter, we will cover the following recipes:

• How to use the concurrent.futures Python module
• Event loop management with Asyncio
• Handling coroutines with Asyncio
• Task manipulation with Asyncio
• Dealing with Asyncio and Futures

Introduction

With the sequential and parallel execution model, there is a third model, called the asynchronous model, that is of fundamental importance to us along with the concept of event programming. The execution model of asynchronous activities can be implemented using a single stream of main control, both in uniprocessor systems and multiprocessor systems.

In the asynchronous model of a concurrent execution, various tasks intersect with the timeline, and all of this happens under ...
