Overview of this book

Python is a versatile programming language that can be used for a wide range of technical tasks—computation, statistics, data analysis, game development, and more. Though Python is easy to learn, it’s range of features means there are many aspects of it that even experienced Python developers don’t know about. Even if you’re confident with the basics, its logic and syntax, by digging deeper you can work much more effectively with Python – and get more from the language. Python Unlocked walks you through the most effective techniques and best practices for high performance Python programming - showing you how to make the most of the Python language. You’ll get to know objects and functions inside and out, and will learn how to use them to your advantage in your programming projects. You will also find out how to work with a range of design patterns including abstract factory, singleton, strategy pattern, all of which will help make programming with Python much more efficient. Finally, as the process of writing a program is never complete without testing it, you will learn to test threaded applications and run parallel tests. If you want the edge when it comes to Python, use this book to unlock the secrets of smarter Python programming.

Scaling horizontally


If we add further nodes to the application, it must add to the total processing power. To create frontend systems that perform more data transmission than computation, async frameworks are better suited. If we use PyPy, it will give a performance boost to the application. Code for Python 3 or Python 2 compatibility using six or other such libraries so that we can use anything available for optimization.

We can use message pack or JSON for message transfer. I prefer JSON for language agnostic and easy-text representation. Workers can be multiprocessing workers for CPU-bound tasks or thread-based for other scenarios.

The system should not store the state but pass it with messages. Everything doesn't need to be in DB. We can take some things out when not necessary.

ZeroMQ (messageQueue): ZMQ is a wonderful library that acts as a glue to connect your programs together. It has connectors for almost all language. You can easily use multiple languages/frameworks to enable their...
