Setting up Cython

Cython is a compiler that converts Python code with the type definition to C code, which still runs in the Python environment. The final output is native machine code, which runs much faster than the bytecode produced by Python. The magnitude of speed-up for Python code is more evident in code that heavily uses loops. In order to compile C code, the first prerequisite is to have a C/C++ compiler such as gcc (Linux) or mingw (Windows) installed on the computer.

The second step is to install Cython. Cython comes just like any other library with a Python module and you can install it using any of your preferred methods (pip, easy_install, and so on). Once these two steps are done, you can test your setup by just trying to call Cython ...
