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.

Summary


In this chapter, we saw various techniques that are used to optimize and profile code. I will, again, point out that we should always focus on first writing the correct program, then writing test cases for it, and then optimizing it. We should write code with optimizations that we know at that time or without optimization the first time, and we should hunt for them only if we need them from a business perspective. Compiling a C module can give a good speedup for CPU-intensive tasks. Also, we can give up GIL in C modules, which can also help us in increasing performance. But, all of this was on single system. Now, in the next chapter, we will see how we can improve performance when the tricks that were discussed in this chapter are not sufficient for a real-life scenario.
