Cython was specially designed as a language that can make writing C extensions for the Python programming language as easy as Python itself. The utility is designed to work with Cython, which is based on the well-known Pyrex, but supports more cutting edge functionality and optimizations.
Some state that this is nothing more than a Python implementation especially since it is capable of compiling all existing Python codes and hence, it gets close to the well-known programming language. While Cython resembles Python in many ways, you should bear in mind that it additionally supports calling C functions and declaring C types on variables and class attributes.
In addition, according to the developer a Cython compiled pybench can run up to 30% faster overall and up to 60% in control structures. At the same time, it scales very well to even greater performance requirements, especially for code that relies heavily on lists, dicts and strings, just to give an example.
This allows the compiler to generate very efficient C code from Cython code. From this point of view, Cython can be considered the ideal language for wrapping external C libraries, and for fast C modules that speed up the execution of Python code.

A Language for Writing Optimized Extension Modules for the Python
Programming Language

Cython was originally designed to be a universal Python extension language. It was designed to allow developers to use C or C++ to speed up their work, and to avoid writing lots of boiler-plate code. It was also created to make writing C extensions for the Python programming language as easy as writing Python itself.
It automatically generates C-like code, but with a Python-like syntax, giving you all the benefits of a high-level interpreted language at the same time as enabling Python calls into C and C++ code.
The syntax is designed to look as close as possible to normal Python, making it easy to read, and making it easy to integrate the generated code with existing Python code. For example, you can call a Cython function from a Python program just like any other Python function. The Cython header files simply need to be used when writing Cython code, and the compiler will be able to turn it into pure C code.
Cython supports operations on primitive C data types like arrays, structured data, strings, and other objects. In addition, it includes data types like integers, floating-point numbers, Python lists, tuples, Dictionaries, and strings.
However, the most significant advantage that Cython has over other compilers is that you can use Cython’s API to define external code. This is done by adding Cython functions to the code. This allows you to call C code libraries from a Python program.
In addition, it can help ensure that the implementation of the APIs is correct by unit-testing it using Cython’s API.
Typical uses for Cython include:

Calling C code from Python programs, which is more efficient than
requiring the user to create call wrappers in a scripting language
Emulating libraries using a mixture of Python and C
Embedding C code, such as a specialized algorithms library
Interfacing with C libraries that will be accessed from a Python
Removing unnecessary allocations from a Python program, since
adding them is a slow operation

However, Cython doesn’t aim to replace the normal Python. Instead, it makes it easier to code in C.
Some of Cython’s capabilities include:

Fast compilation, including most type declarations.
Unrestricted use of Python types on C variables and C variables
on Python variables.
Declaring C variables


Cython is a free and open source program that allows you to add a Python programming language to the libraries of C++, Java, Pascal and Fortran. These libraries can be used for development. They have the disadvantage of being difficult to distribute and update, especially with Python or Cython. There are also disadvantages with writing in Cython because it does not generate directly a binary program, but only a code file.
This leads to the following advantages:
– You can write Python code by hand in the project but Python compiles it immediately.
– The result is directly C code. That is, the binary code is generated by the Cython command.
The following instructions should help to download and install Python 3.4.1 on macOS 10.13.

Download Python 3.4.1 from here

Open the terminal

Next, we get the folder. Once the installation is finished, it opens the Applications folder.
If you want to get Python 3.4.1, then click on it.
On the page that appears, we need to rename it to
Because the and Python are slightly confusing on the website, you will probably put the command to rename it to python-3.4.1-MacOSX.

It is necessary to perform the update using the command terminal because we need to download Python and install it in the right directory.

cd /Library/Frameworks

Once we have done this, we will choose the directory in which to save the

mv /Applications/Python 3.4.1

There we need to open the Terminal and type the command to rename the to Python 3.4.1.

Open the terminal

cd /Applications

Open the bin folder

cd /Applications/Python 3.4.1

Next, open the terminal with the command.

source bin/activate

Command App

Type pip3. To Install pip3

sudo apt install python3.4-dev


Next, open the virtual environment by typing the command python3.4. To create the virtual environment, we will need to create a folder named virtual environment.

virtualenv venv

Command prompt

Virtual Environments:

The virtual environment will contain all the requirements to run Cython.

Cython is a language built on the Pyrex ( language. A Cython compiler takes C or C++ code and compiles it to Python.
Cython simplifies the process of writing “Python extensions” for C or C++ programs. Python extensions are programs which can extend the capabilities of the Python language. Cython does this by compiling the Python source to C.
As a result of the compilation, Cython creates Python modules (.py) which are Python source code that provides a Python interface to the C or C++ code.
This means that Python runs the C or C++ functions or methods of the C or C++ classes or modules through the code of the Python classes.
The source code of the Python module is compiled by the Cython compiler. You can use Cython to add, to modify, and to enhance the capabilities of existing Python programs. This allows you to add important features to Python modules which have a need for speed or have a requirement for large data sets. Cython is geared toward extending existing Python features and is for programmers who like Python, but would like to add new features to Python more quickly and with fewer limitations.
Cython Example:
Simple examples of Cython are easy to find. In reality, Cython has a lot of powerful features which allow you to optimize existing Python programs for specific applications.
Custom Function Py_Increment(int j) is Cython / Python
#cython: boundscheck=False
#cython: wraparound=False
#cython: cdivision=True
def __cinit__(self):
def __dealloc__(self):
def Py_Increment(self, j):
for i in range(j):
def Py_Decrement(self, j):
for i in range(j, -1, -1):


The Cython documentation describes it in the following way:

Cython is designed to be a language that can easily interface with
C/C++ programs.

What’s New in the?

Cython is a Python dialect that adds Cython code compilation that gives you fast C modules or C extension modules for Python.

Features of Cython:

A powerful hybrid language: powerful Cython.
Hybrid language that enables you to write Cython code that works in the same way as C and Python at the same time.
Compile Python code to C-like language, while retaining the speed and ease of Python.

Cython Example:

Compile Python to Cython:

# Cython code:
import numpy as np

def function_that_gives_output(values):
avg = np.average(values)
print(‘average: %f’ % avg)

cdef extern from “math.h”:
double sqrt(double x)

def main():
cdef np.ndarray values = np.random.rand(1000000)

Yes, it is a pretty much a similar to PyPy.

PyPy is a next generation interpreter for Python. It is fast,
and, crucially, also safe. It is written in a mix of Python and C++, and
is extensible both in source and binary forms. Its goal is to be an
implementation of the Python standard library.
