longDescription = ''
Cython is an optimising static compiler for both the Python programming
language and the extended Cython programming language (based on Pyrex). It
makes writing C extensions for Python as easy as Python itself.
Cython gives you the combined power of Python and C to let you:
- write Python code that calls back and forth from and to C or C++ code
natively at any point.
- easily tune readable Python code into plain C performance by adding
static type declarations, also in Python syntax.
- use combined source code level debugging to find bugs in your Python,
Cython and C code.
- interact efficiently with large data sets, e.g. using multi-dimensional
NumPy arrays.
- quickly build your applications within the large, mature and widely used
CPython ecosystem.
- integrate natively with existing code and data from legacy, low-level or
high-performance libraries and applications.
The Cython language is a superset of the Python language that additionally
supports calling C functions and declaring C types on variables and class
attributes. This allows the compiler to generate very efficient C code
from Cython code.
