Abstract - Python is an interpreted, high-level, general-
purpose programming language. Created by Guido van
Rossum and first released in 1991, It is used for both
learning and real-life programming. It is easy to learn as
most of the commands are similar to normal word used by
humans (e.g. To print any statement or any value we simply
write “print (statements)”). Many of the famous application
are developed using python (e.g. Instagram, Dropbox.).
Python might have a great scope in future so it’s a very
important language. In this paper we will see why python is
so important and why we should learn in.
Key words - Python, Python programming, high level
programming language, Real world programming.
INTRODUCTION
Python is a general-purpose programming language also
known as scripting language. It is an open source language.
Python features a dynamic type system and automatic
memory management. It supports multiple programming
paradigms’, includingobject-oriented,imperative,functional
and procedural, and hasa largeandcomprehensivestandard
library. It has a design philosophy that emphasize code
readability notably using significant whitespace i.e. scope of
particular set of codes are determined by using whitespaces
only unlike other programming languages where curly
braces are used. Python is also known as interpretive
language, meaning you don’t have to write the programs.
You can just enter statements into python environment and
they’ll execute.
Software developer’s choice
According a article on Google posted on zdnet.com Python
has grown to become one of the top programming languages
in the world, with more developers than evernowusingitfor
data analysis, machine learning, DevOps and web
development.
Now a days use of Data analysis and machine learning have
increased so for that, Data analysis and machine learning in
particular have moved up in python developers’ priorities,
according to 2018 Python developer survey.
Today, 58 percent who uses python do so for data analysis,
up from 50 percentlastyear,overtakingwebdevelopmenton
52 percent. The other rapidly rising uses for python are
machine learning and DevOps.
Worlds one of the most popular coding language
The popularity of Python has risen steadily over the past 15
years, finally breaking the top 5 on the Tiobe Index a few
years ago. This is because Python is a major language in
some of most exciting technologies today. Machine learning,
artificial intelligence (AI), Big Data, and Robotics all rely
heavily on Python (Robotics also relies on C for its use in
systems programming). Cyber Security, one of the top
software challenges of our time, is also driven by Python.
It’s surprising how simple Python is to learn. It’s now
the most popular introductory language taught in
universities and often picked up by experienced developers
as a second or third language.
Growth on Python Machine Learning Jobs
Python is good for beginners
Python should be your first programming language because
you will quickly learn how to think like a programmer.
Python is very readable. You won’t waste a lot of time
memorizing the complex syntax that other programming
languages such as C, C++, etc. will present you. Instead, you
will be able to focus on learning programming concepts and
paradigms. Onceyouunderstandthosetoolsyoucanmoveon
to other more powerful, specific languages and readily
understand a given piece of code.
Once you learn the basicsyoustartgettinginterestedtoknow
more about python, this is the time when you try to get more

deeper into learning it. You start using different librariesand
modules. One can work on graphics in python using Python
Imaging Library, make games with libraries such as Pygame
or Pyglet,
Another important thing is that it comes bundled with IDLE.
IDLE is both an interactive shell and an integrated
development environment (IDE) for Python i.e. it is easy to
write and run python programs.
Features:
1. Easy to learn:
Python is very easy to use and high-level language.
Its statements consist of normal words so it
becomes easier for any beginner to understand the
code. For example, to print any string in python we
use keyword “print” instead of complex keywords
such as “cout” in C++, “System.out.print” in Java,etc.
Thus, it is programmer friendly language.
2. Expressive Language:
Python language is more expressive. The sense of
expressive is the code is easily understandable. In
languages like C, C++, etc. programmers sometimes
use comments to make others programmer
understand what’s going on in that part of the code
but in Python use of comments is very less because
one can get an idea of the code by looking at it.
3. Interpreted Language:
Python is interpreted language i.e. interpreter
executes the code line by line at a time. This makes
debugging easy. Whenever interpreter finds an
error it stops executing the code at that statement,
due to this the programmer can find the statement
that contains error easily and don’t have to search
for errors as in other languages like C. C++, etc.
4. Cross-platform language:
Python can run equally on different platforms such
as Windows, Linux, Unix, Macintosh etc. We don’t
have to write code again to run it on another
platform. If we have a code written to run on
Windows operating system we can execute the
same code on other operating system suchasLinux,
UNIX etc. without making changesinthecode. Thus,
Python is a portable language.
5. Free and Open Source:
Python language is freely available
(www.python.org), we don’t need any special
license or need to pay for it. The source-code is also
available. Even though all rights of this programare
reserved for the Python institute, but it is open
source and there is no limitation in using, changing
and distributing. You can freely use and distribute
Python, even for commercial use. Therefore, it is
open source.
6. Object Oriented Language:
Python supports object- orientedlanguage.Concept
of classes and objects comes into existence.
Everything in Python is an object. Object oriented
programming (OOP) helps you solve a complex
problem intuitively. With OOP, you are able to
divide these complex problems into smaller sets by
creating objects.
Python is a multi-paradigmprogramminglanguage:
object-oriented programming and structured
programming are fully supported. Python uses
dynamic typing and a combination of reference
counting and a cycle-detecting garbagecollectorfor
memory management. An important feature of
Python is dynamic name resolution (late binding),
which binds method and variable names during
program execution. Python was designed to be
highly extensible. Python can also be embedded in
existing applications that need a programmable
interface.
7. Extensible:
It implies that other languages suchasC/C++canbe
used to compile the code and thus it can be used
further in your python code
8. Large Standard library:
Python has a large and broad library. It reduces the
programmer’s efforts as the codes are already
written. It can help to do regular expressions,
documentation generation, unit testing, threading,
databases, web browsers, email, xml, html, GUI, Tk
etc.
9. GUI programming support:
Graphical user interfaces can be developed using
Python. Tkinter is a basic interface for designing
GUIs in Python. Tkinter is a standard object-
oriented interface that is distributed with Python
interpreter. It provides the essential tools for
designing GUI.
10. Integrated:
It can be easily integrated with languages like C,
C++, JAVA etc.

Drawbacks:
Though python has many features and is one of the fastest
growing language it also has some drawbacks.
1. Speed:
Python is interpreted language and is slow as
compared to C/C++ or Java. Unlike C or C++, it’s not
closer to hardware because Python is a high-level
language. As we all know that compilation and
execution help to work normally, but in this case,
execution of Python takes place with the help of an
interpreter instead of the compiler as we have seen
that Python code is executed line by line, which
causes it to slow down.
2. Mobile Development:
However, Python is strong in desktop and server
platforms, that is it is an excellent server-side
language but for the mobile development, Python is
not a very good language which means it is a weak
language for mobile development.
3. Memory Consumption:
For any memory intensivetasksPythonisnotagood
choice. That is why it is not used for that purpose.
Python’s memory consumption is also high, due to
the flexibility of the data types.
4. Database Access: Python is a robust programming
language with minimal stress and worries. But, this
language is highly insecure and can be used only at
one’s own risk.
Even though it has some drawbacks but, due to its features it
can be neglected.
Top Companies Embracing Python Programming
Language
Google: Google’s first search engine and the entire stack
were written in Python. It was developed in the late 90s
which uses old-school they still use Python extensively.
Facebook: Facebook uses the Python language in their
Production Engineering.
NASA: NASA uses Workflow Automation Tool which is
written in Python.
Nokia: Nokia which is a Finnish company is a popular
telecommunication industry. It uses Python for its platform
such as S60.
IBM: IBM an American-based multinational computer
manufacturer also uses Python for their factor tool control
applications.
SGI Inc: SGI (Silicon Graphics International) usesPython for
its Linux installer.
Walt Disney Feature Animation: This animation studio
uses Python as a scripting language for their animations.
Yahoo! Maps: It is a map developed by Yahoo! and many of
its services are also written in Python.
Future of Python
Python has been voted for the most favorite programming
language of all time. It is undoubtedly beating other
programming languages. It has been used for developing
almost every kind of applications whether it is web
applications or game applications. Numerous programmers
have increased the use of Python programming languages
and it is certainly used worldwide. Python programmers
would be the most demandable in the future of IT industries
which makes Python future brighter.
CONCLUSION
From the above we get to know that Python is not only easy
but also very important. The most important thing is that it
has a great scope in future. Most of the beginners in field of
programming wish to work in topcompaniessuchasGoogle,
Facebook, etc. and these companies also use pythonsoifyou
want to fulfill your wish learning Python may prove to be an
important step for it. The use of python has kept on
increasing so it might also help in your job.
