Expert Python Programming - Third Edition

By: Michał Jaworski, Tarek Ziadé

Overview of this book

Python is a dynamic programming language that's used in a wide range of domains thanks to its simple yet powerful nature. Although writing Python code is easy, making it readable, reusable, and easy to maintain is challenging. Complete with best practices, useful tools, and standards implemented by professional Python developers, the third edition of Expert Python Programming will help you overcome this challenge. The book will start by taking you through the new features in Python 3.7. You'll then learn the advanced components of Python syntax, in addition to understanding how to apply concepts of various programming paradigms, including object-oriented programming, functional programming, and event-driven programming. This book will also guide you through learning the naming best practices, writing your own distributable Python packages, and getting up to speed with automated ways to deploy your software on remote servers. You’ll discover how to create useful Python extensions with C, C++, Cython, and CFFI. Furthermore, studying about code management tools, writing clear documentation, and exploring test-driven development will help you write clean code. By the end of the book, you will have become an expert in writing efficient and maintainable Python code.

Event-driven architectures

From event-driven applications, there is only one minor step to event-driven architectures. Event-driven programming allows you to split your application into isolated components that communicate with each other only by passing events or signals. If you already did this, you should be also able to split your application into separate services that do the same, but transfer events to each other, either through some kind of IPC mechanism or over the network.

Event-driven architectures transfer the concept of event-driven programming to the level of inter-service communication. There are many good reasons for considering such architectures:

  • Scalability and utilization of resources: If your workload can be split into many order-independent events, architectures that are event-driven allow the work to be easily distributed across many computing nodes ...
