Python

Python is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms.

Python is the fastest-growing major backend language

Stack Overflow has dubbed it “the fastest-growing major programming language” on more than one occasion. Python has garnered increasing traffic in Stack Overflow’s site since late 2011, as well as in their Developer Survey. Back in 2013, It ranked 6th in popularity with just under 22% of survey takers having declared to use it. By 2017, it had finally risen to 5th place and, this year, it has actually edged out Java earning 4th place among the most popular technologies for Stack Overflow users. This again translates into more available resources to work with this particular programming language.

Characteristics

  • It supports functional and structured programming methods as well as OOP.
  • It can be used as a scripting language or can be compiled to byte-code for building large applications.
  • Python provides very high-level dynamic data types and supports dynamic type checking.
  • It supports automatic garbage collection.
  • It can be easily integrated with C, C++, COM, ActiveX, CORBA, and Java.

Applications

As mentioned before, Python is one of the most widely used language over the web. I’m going to list few of them here:

  • Easy-to-learn − It has few keywords, simple structure, and a clearly defined syntax. This allows the student to pick up the language quickly.
  • Easy-to-read − Python code is more clearly defined and visible to the eyes.
  • Easy-to-maintain − Python’s source code is fairly easy-to-maintain.
  • A broad standard library − Python’s bulk of the library is very portable and cross-platform compatible on UNIX, Windows, and Macintosh.
  • Interactive Mode − It has support for an interactive mode which allows interactive testing and debugging of snippets of code.
  • Portable − Python can run on a wide variety of hardware platforms and has the same interface on all platforms.
  • Extendable − You can add low-level modules to the Python interpreter. These modules enable programmers to add to or customize their tools to be more efficient.
  • Databases − It provides interfaces to all major commercial databases.
  • GUI Programming − Python supports GUI applications that can be created and ported to many system calls, libraries and windows systems, such as Windows MFC, Macintosh, and the X Window system of Unix.
  • Scalable − Python provides a better structure and support for large programs than shell scripting.

Python Features

Python provides many useful features which make it popular and valuable from the other programming languages. It supports object-oriented programming, procedural programming approaches and provides dynamic memory allocation. We have listed below a few essential features.

1) Easy to Learn and Use

Python is easy to learn as compared to other programming languages. Its syntax is straightforward and much the same as the English language. There is no use of the semicolon or curly-bracket, the indentation defines the code block. It is the recommended programming language for beginners.

2) Expressive Language

Python can perform complex tasks using a few lines of code. A simple example, the hello world program you simply type print(“Hello World”). It will take only one line to execute, while Java or C takes multiple lines.

3) Interpreted Language

Python is an interpreted language; it means the Python program is executed one line at a time. Hence, the advantage of being interpreted language, it makes debugging easy and portable.

4) Cross-platform Language

Python can run equally on different platforms such as Windows, Linux, UNIX, and Macintosh, etc. So, we can say that Python is a portable language. It enables programmers to develop the software for several competing platforms by writing a program only once.

5) Free and Open Source

It is freely available for everyone on its official website. It has a large community across the world that is dedicatedly working towards make new python modules and functions. Anyone can contribute to the Python community. The open-source means, “Anyone can download its source code without paying any penny.”

6) Object-Oriented Language

Python supports object-oriented language and concepts of classes and objects come into existence. It supports inheritance, polymorphism, and encapsulation, etc. The object-oriented procedure helps to programmer to write reusable code and develop applications in less code.

7) Extensible

It implies that other languages such as C/C++ used to compile the code and thus it can be used further in our Python code. It converts the program into byte code, and any platform can use that byte code.

8) Large Standard Library

It provides a vast range of libraries for the various fields such as machine learning, web developer, and also for the scripting. There are various machine learning libraries, such as Tensor flow, Pandas, Numpy, Keras, and Pytorch, etc. Django, flask, pyramids are the popular framework for Python web development.

9) GUI Programming Support

Graphical User Interface used for the developing Desktop application. PyQT5, Tkinter, Kivy such libraries which used for developing the web application.

10) Integrated

It can be easily integrated with languages like C, C++, and JAVA, etc. Python runs code line by line like C,C++ Java. It makes easy to debug the code.

11. Embeddable

The code of the other programming language can use in the Python source code. We can use it’s source code in another programming language as well. It can embed other language into our code.

12. Dynamic Memory Allocation

In Python, we don’t need to specify the data-type of the variable. When we assign some value to the variable, it automatically allocates the memory to the variable at run time.

Running Python

There are different ways as follows:

1. Interactive Interpreter

You can start Python from Unix, DOS, or any other system that provides you a command-line interpreter or shell window.

$python # Unix/Linux
or
python% # Unix/Linux
or
C:> python # Windows/DOS

2. Script from the Command-line

A Python script can be executed at command line by invoking the interpreter on your application, as in the following −

$python script.py # Unix/Linux

or

python% script.py # Unix/Linux

or 

C: >python script.py # Windows/DOS
