Introduction to Python | Python Basics | Python For Beginners | Why Python Programming | Intellipaat


So in this session we’ll start with a
basic of Python where we’ll be learning like what is Python, who invented Python and why did it named it so. I will also tell about why you should learn Python
and what are the popular companies and tech giants in the market who are already
using it so without delaying any further let’s start this session. Let me start
this session with some facts and research based on Python.
According to stack overflows 2018 developer survey, it was found that
Python is a most wanted programming language of 2018. Even if you talk about
the career in Python, Python developers are in a great demand for a wide range
of jobs all over the world these include machine learning, databases, data analysis, cloud infrastructures website designing, web scraping, security,
mobile developments and many more let me just give you an example, if you
search for a Python developer job on any major job website like indeed.com
or monster.com you will find thousands of job opportunities out there. Based on
Indeed March 2018 data, the average salary of a Python developer in US was
around 115 thousand and 835. Such high average salary indicates that many
companies are competing to hire knowledgeable Python developers and it
also supports the fact that python is an in-demand skill okay
so let’s start our session with introduction to Python. So what is Python
well python is a high-level object-oriented programming language for
general-purpose programming. It is one of the most widely used high-level
programming language and is well known for executing basic tasks with less code
which makes it more compact and an economical language to learn. If you see
Python code is often three to five times shorter than the Java codes and around
five to ten times shorter than C++ codes
well if you talk about its history it was developed by Guido van Rossum in the
year 1991 and since then it’s open-source community is still growing
so how do you think he came up with this name? wasn’t the cause of a snake? well
No. Rossum named Python over the name of a sitcom TV series Monty Python
Flying Circus it seems he was highly impressed with
the show right so these are some of the high-level introduction to Python. Now a
question might arise in your mind that what made Python so popular or why you
should learn it. So let’s discuss at one by one. So the first point we have is
simple and easy to learn. Well if you compare Python with any other language
for example in Java or C++ you’ll find that it’s syntax is way lot easier than
them. You don’t have to worry about the missing semi commas and its
syntax is more readable and you are safe from writing multiple lines of code just
for printing a statement like in case of Java. If you talk about Python all you
need to write it is just one line of statement. For example print and within
the double quotes mentioned whatever you want to print so this’s how it is
simple and easy to learn. The next point comes the carrier opportunity. Well like
I told you in the beginning of this video itself that Python has a huge
career opportunity in the IT industry almost every other IT company be it a
startup or a multi-billion a company are using Python in some or the other
ways so if you are a Python developer you will be on a huge demand for a wide
range of jobs in the domain of machine learning, databases, data analysis, cloud
infrastructure, website designing, website reliability, testing, scraping, security,
mobile developments and many more if you don’t trust my words just go and look
out for Python developer job on any major job website you will find
thousands of job opportunities out there with average salary of around one hundred
and sixteen thousand dollars this indicates that there are many companies
out there who are competing to hire a knowledgeable Python developer for them
so yeah you have a huge career opportunity in Python. All depends on
your skill all right next is large open source
community, well if you become a Python developer and when you are stuck or you
want to learn something new then you don’t have to worry about it you will
find a large number of resources like reference manuals, books, tutorials ,videos,
forums etc out there on the internet. If you have any doubt of some technical
issues you can directly seek help from thousands of Python community members on
forum, Twitter or Facebook and pretty much everywhere now since Python
is an open source community you will always find people who are trying to
improve it keeping it fresh and up-to-date with current trends and
bringing out newer version of the language right so yeah it has a damn
large open source community. Next we have is reliable and efficient. Ask any Python
developer or anyone who has ever use the language and they will agree that it’s
speedy, reliable and more efficient. You can work with and deploy Python
applications in nearly any environment and there’s little to no performance
loss no matter what platform you work with. Again because it’s versatile this
also means that you can work across several domains including web
development, desktop application, mobile applications and many more. You are not
bound to a single platform or domain as it offers the same experience almost
everywhere alright. So next we have is the extensive library
well Python has a huge set of library lists which would be useful for any
programmer interested in Python depending on their area of interest. For
example you have numpy for scientific computing, plotlib for data
visualization, NLTk for natural language processing, django for web framework, Pygem for game development and there are many more it can be using a lot of places and has
a wide variety of application like for web development you can use Python web
framework like django flask and tomado if you are into developing desktop
application you can go with pi GTK and cocoa or if you are planning to use
Python in the field of machine learning or deep learning or data science you’ll
find many Python libraries for it like SKlearn, tensorflow, theano, nltK and many
more. If you talk about cloud and devops you can use OpenStack Python software
development kit which is generally used to write Python automation scripts to
create and manage resources in your OpenStack cloud. You can even use a
Python library named fabric for streamlining the use of SSH for
application development or system administration tasks alright. last what
we have is Hardware programming. Next if you are planning to switch over to
hardware programming you have raspberry pi to connect your project to the real
world with python well now that you know how important is Python to the world
let’s see the popularity of Python and Industry. Well big tech giants are using
Python in fact python is one of the Google’s favorite languages they are
always hiring expert in it and they have even created many of their popular
products with it but I don’t think I should again mention that since many big
companies like Yahoo, Facebook, Netflix Dropbox, YouTube, BitTorrent, NASA and many
other rely on Python developers so these companies are always in search of
talented professionals who have already worked on and has some experience in
Python, there is and there always be a demand for Python developers and Python
web developers and they are even offered some decent packages well this was all
about the background check of Python so this was all for this session. In our
next session we will learn about how you can install and setup Python on your
system. Thank you
