What's this?-cython language Brief introduction

Cython is a programming language that can write both C and Python, and his goal is to become a superset of the Python language , providing high-level, object-oriented, functional, dynamic programming capabilities for Python. Unlike pure Python, it provides a declaration statement for a variable type. Cython is also a compiler that compiles python and compiles code for Cython languages. Its goal is to have pythoner write C extensions as simple as writing Python .

Cython can:

• Compile your Python code into a C language file, and also roll back from a C language file to a python file
• By adding a type declaration, you can simply convert the readable Python code to an efficient C code
• Raise bugs at the level of the source
• Ability to efficiently interact with large data sets, such as using multidimensional numpy sequences
• Quickly write your app by using the Cython ecosystem
• Simple integration of common C libraries and programs to develop

The Cython compiler is able to compile the vast majority of Python code, and the generated C code, usually at run speed, can get a very noticeable boost. So in the Cython language we allow some of the features in C to exist and translate it into very efficient C code. The existence of a variable type declaration statement has two purposes in Cython: to convert a Python variable that is dynamically transformed into a static but efficient C variable, and also to enable the Python language to use the efficient C-language function library. Cython thus combined the two systems of C with Python, making him a very versatile programming language.

This is the Cython compiler. Pyx---C-- -So/.dll

A simple example of Cython:

First write a file named Helloworld.pyx

Print (' Hello world! ')

And then we'll write a setup.py file for it.

From Distutils.core import setupfrom cython.build import cythonizesetup (    ext_modules = cythonize ("Helloworld.pyx") )

Run command: Python setup.py build_ext--inplace

At this point you will see a helloworld.so or Helloworld.dll file generated under the current folder.

Enter the Python IDE, enter import HelloWorld try and we'll see Hello world! The display.
