Learning Cython Programming (Second Edition) - Second Edition

By: Philip Herron

Overview of this book

Cython is a hybrid programming language used to write C extensions for Python language. Combining the practicality of Python and speed and ease of the C language it’s an exciting language worth learning if you want to build fast applications with ease. This new edition of Learning Cython Programming shows you how to get started, taking you through the fundamentals so you can begin to experience its unique powers. You’ll find out how to get set up, before exploring the relationship between Python and Cython. You’ll also look at debugging Cython, before moving on to C++ constructs, Caveat on C++ usage, Python threading and GIL in Cython. Finally, you’ll learn object initialization and compile time, and gain a deeper insight into Python 3, which will help you not only become a confident Cython developer, but a much more fluent Python developer too.

PyPy has become a popular alternative to the standard Python implementation. More importantly, it is now being used by many companies (small and large) in their production environments to boost performance and scalability. How does PyPy differ from normal CPython? While the latter is a traditional interpreter, the former is a full-fledged virtual machine. It maintains a just-in-time compiler backend for runtime optimization on most relevant architectures.

Getting Cythonized modules to run on PyPy is dependent on their cpyext emulation layer. This isn't quite complete and has many inconsistencies. But, if you are brave and up to trying it out, it's going to get better and better with each release.
