From Python To Cython

Graphical depiction of going from Python to Cython

This longer post will show you some of the coding skills you’ll need for turning your existing Python code into the Python-C hybrid we call Cython. In doing so, we’ll be digging into some C static data types, to see how much faster Python code will run, and restructuring some Python code along the way for maximum speed.

With Cython, all the benefits of Python are still yours – easily readable code, fast development cycles, powerful high level commands, maintainability, a suite of web development frameworks, a huge standard library for data science, machine learning, imaging, databases and security, plus easy manipulation of files, documents and strings. You should still use Python for all these things – these are what Python does best. But you should also consider combining them with Cython to speed up the computationally intensive Python functions that needs to be fast. Continue reading “From Python To Cython”

The Toolkit

SpannersOK, first things first. What tools will I be using?

After talking to a good friend who is an experienced coder, I decided on the following:


Spyder, running Python 3. It seems to have everything I need, including a good debugger, a variable explorer, hot-linking to function definitions, auto-completion typing, Matplotlib, QT, plus a choice of either a Python and iPython console (each with their different strengths). The bundle I went with is Spyder for WinPython-64bit (WinPython-64bit- The QT will be useful later.
