Build software that combines Pythonâ??s expressivity with the performance and control of C (and C++). Itâ??s possible with Cython, the compiler and hybrid programming language used by foundational packages such as NumPy, and prominent in projects including Pandas, h5py, and scikits-learn. In this practical guide, youâ??ll learn how to use Cython to improve Pythonâ??s performanceâ??up to 3000xâ?? and to wrap C and C++ libraries in Python with ease. Author Kurt Smith takes you through Cythonâ??s capabilities, with sample code and in-depth practice exercises. If youâ??re just starting with Cython, or want to go deeper, youâ??ll learn how this language is an essential part of any performance-oriented Python programmerâ??s arsenal.
