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.

Using fast libraries


Key 3: Use easy drop-in faster libraries.

There are libraries out there that can help a lot in optimizing code, rather than writing some optimized routines yourself. For example, if we have a list that needs to be fast at FIFO, we may use the blist package. We can use C versions of libraries, such as cStringIO (faster StringIO), ujson (faster JSON handling), numpy (math, and vectors), and lxml (XML handling). Most of the libraries that are listed here are just a Python wrapper over C libraries. You only need to search once for your problem domain. Other than this, we can make a C, or C++ library interface with Python very easily, which is also our next topic.
