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.

Chapter 5. Advanced Cython

Throughout this book, we have exclusively been mixing C and Python together. In this chapter, we will delve into C++ and Cython. With every release of Cython C++, the support has improved. This is not to say that it's not ready for use yet. In this chapter, we will cover the following topics:

  • Make native C++ classes callable from Python.

  • Wrapping C++ namespaces and templates

  • How exceptions can be propagated to and from C++ and Python

  • C++ new and del keyword

  • Operator overloading

  • Cython gil and nogil keywords

We will wrap up this chapter by embedding a web server into a toy C++ messaging server.
