so this is the first lecture of ourĀ
python code so you can say python courseĀ
we will see in this video introductionĀ
to python rightĀ
like you can say some features of thisĀ
language application areas who are usingĀ
this python why this is so popularĀ
nowadays some features this kind ofĀ
thing we'll be discussing in this videoĀ
about python or pythonĀ
i'll pronounce it as python right okayĀ
now see python is nowadays the mostĀ
popular programming language but you canĀ
say it is the fastest growingĀ
programming language nowadays it's notĀ
like that it is new language because youĀ
you know you think thatĀ
recently it is it has become so popularĀ
so it is aĀ
new language noĀ
the concept of python came into pictureĀ
in 1989Ā
and even javaĀ
was you know the concept of java or cameĀ
into picture in 1995 so it is beforeĀ
javaĀ
right butĀ
recently in past few years likeĀ
python has become so much popular andĀ
why so that also will discussĀ
right now basically in every area pythonĀ
is being used right now the main areasĀ
are machine learning data scienceĀ
artificial intelligence see nowadays theĀ
data is a big problem many companiesĀ
like you can say your facebookĀ
youtube any shopping websitesĀ
they are havingĀ
data of billions of users right and howĀ
they manage that dataĀ
and one more thing is what see i thinkĀ
you have noticedĀ
if you suppose uhĀ
nowadays iĀ
you know a search for especially chickenĀ
carry kurtasĀ
rightĀ
soĀ
i have i've been looking for theseĀ
kurtas on two or three website shoppingĀ
websites and whenever i open any otherĀ
website you know for studyĀ
that kind of thingĀ
soĀ
those relevant ads they show meĀ
now ads of those chicken curry kurtasĀ
and all so have they come to know theĀ
advertisers like how they come to knowĀ
that i'm interested in buying thoseĀ
chicken curry kurtasĀ
so this is what they have analyzed myĀ
dataĀ
howĀ
many websites i have visited in whichĀ
how you know i'm interested so they haveĀ
analyzed that data they have collectedĀ
my data they have analyzed that data andĀ
according to that they have mind you canĀ
say someĀ
pattern they have formedĀ
and they come to they come to know thatĀ
i am interested in chicken keri kurta soĀ
they show me the relevant adĀ
i think you must have noticed this thingĀ
alsoĀ
rightĀ
so this task is what this analysis ofĀ
data and allĀ
in this also python is being usedĀ
rightĀ
soĀ
in many areas this is one application ofĀ
this language and see in many areas likeĀ
whether it's software development it'sĀ
web development software testing machineĀ
learning artificial intelligence dataĀ
science game development making of anyĀ
apps mobile apps desktop app websites orĀ
web apps anything hacking even hackingĀ
in many areasĀ
right now python is being used and it'sĀ
not like that small companies are usingĀ
this language no the big giantsĀ
companies are using this language maybeĀ
the main language or supportive type ofĀ
language as a support languageĀ
you can select like google uh youtubeĀ
cura instagram these companies are usingĀ
these big giants are using this languageĀ
rightĀ
and the person who are using itĀ
researchers scientistsĀ
software developers software engineersĀ
software testers game developersĀ
mainlyĀ
data analystĀ
and even school going kidsĀ
they are alsoĀ
learning or you can see using thisĀ
languageĀ
seeĀ
becauseĀ
you know researchers and scientists theyĀ
want usĀ
like they don't want to you know uhĀ
utilize or you can say wasted their timeĀ
by learning a complicated language andĀ
python is easy language so they talkĀ
theyĀ
went for this language python languageĀ
so that is why recently this this fieldĀ
is a you know on boom machine learningĀ
artificial intelligence data scienceĀ
this kind of thing so that is why withĀ
that field python came into pictureĀ
because they these kind of peopleĀ
researchers scientists so they areĀ
working in this field they want a simpleĀ
language to work on right they don'tĀ
want to waste their time on learning aĀ
complicated type of language python isĀ
very simple very easy to understandĀ
language so they took it for thisĀ
language and that is why this uhĀ
language has become so much popularĀ
within the you know recent years soĀ
white has become so popular becauseĀ
first thing is it is easy to learn easyĀ
to understand and it has wide range ofĀ
applications i have told you in how manyĀ
areas almost in every areaĀ
it's been usedĀ
second thingĀ
you can write down you can solve anyĀ
problem withĀ
fewer lines of code suppose you want toĀ
print hello world in c languageĀ
so that those header files main functionĀ
and printf hello one in c plus plus alsoĀ
header files std name space std mainĀ
function and all in javaĀ
those you can say the main functionĀ
system uh sorry public static void meanĀ
then system dot outdoor printer and thenĀ
hello world this kind of thing inĀ
python simply what you need to writeĀ
printĀ
hello worldĀ
that's itĀ
nothing else a simple lineĀ
nothing elseĀ
soĀ
in fewer lines of code you can solveĀ
complex problemsĀ
right and more easily you can understandĀ
this course so it willĀ
you know save your time alsoĀ
another benefit and it is high levelĀ
language you don't need to be awareĀ
about those memory management type ofĀ
thing like in c you have to aware youĀ
have to you know keep track of you haveĀ
to manage the memory manually but hereĀ
automatic memory management is there itĀ
is high level language so you can doĀ
moreĀ
withĀ
lessĀ
right with the writing you can say lessĀ
code you can do more in this it isĀ
object-oriented programming language butĀ
it's not like that it doesn't supportĀ
that paradigm procedural and functionalĀ
it supports multiple paradigmsĀ
object-oriented procedural as well asĀ
functionalĀ
right it is multi-paradigm language itĀ
is general purpose language almost inĀ
every fieldĀ
for making everything you can use thisĀ
languageĀ
it's multi-purpose languageĀ
it isĀ
interpreted language these are someĀ
features of python you can just noteĀ
down these features so it is also pythonĀ
is interpreted language without compiledĀ
languageĀ
rightĀ
and one more feature of this it is openĀ
source right so that is why it is havingĀ
a huge community and rich library manyĀ
illĀ
you know inbuilt packages modulesĀ
functions thoseĀ
you can use in your program withoutĀ
writing those functions from scratchĀ
because it is open source anyone canĀ
contributeĀ
in this right they can write down theirĀ
packages or functions or modules andĀ
they can contribute it is open sourceĀ
anyone can useĀ
those inbuilt functions libraries andĀ
allĀ
right like in cnc plusĀ
also we have some libraries in thereĀ
predefined functions are there these areĀ
already defined function like uh ifĀ
for string concatenation we use directlyĀ
a function str tap so the definition ofĀ
that function is already in thoseĀ
libraries you don't have to write downĀ
the definition of that function youĀ
don't have to tell the compiler you justĀ
use that header file string dot h andĀ
you can call that function because it isĀ
already been defined in the library byĀ
someĀ
other people so by someone elseĀ
so sameĀ
it is also having rich library becauseĀ
it is open source soĀ
and huge community it is having if youĀ
are finding any difficulty in thisĀ
so there are many forums discussionĀ
forums you can post your queries andĀ
definitely you will get answer forĀ
example some libraries are you can sayĀ
numpy pandas tensorflow for machineĀ
learning and data science while in thisĀ
field they use that library seeĀ
basically libraries are whatĀ
some codes are written codes so for someĀ
basic functions are written on thoseĀ
libraries so that programmers don't haveĀ
to write down those function fromĀ
scratch and they can reuse thoseĀ
functions in their own program right soĀ
thatĀ
obviously it will save time of anyĀ
programmer right because they are usingĀ
they are reusing that functionĀ
like for making chapatis you need attaĀ
right so just go to any shop maybe youĀ
can buy whole wheat orĀ
atta right but the process behind thatĀ
thing generally farmers do that processĀ
that long processĀ
right they have done for youĀ
so they have built those things for youĀ
you just have to go and buy you canĀ
reuse that you don't have to do theĀ
whole process from scratch because itĀ
will take definitely long timeĀ
and you don't know definitely most ofĀ
you don't know how toĀ
do that farming processĀ
so same thing those inbuilt librariesĀ
packages modules functions are thereĀ
programmers can reuse those functionsĀ
and so it saves the time of programmersĀ
and many frameworks are also there likeĀ
django flashĀ
if you are interested in web developmentĀ
rightĀ
and i told you like automatic memoryĀ
management is there in this languageĀ
right and it is extensible languageĀ
right you can extend you can supportĀ
more features can be supported you knowĀ
can be added like more libraries orĀ
functions can be added because it isĀ
open source anyone can contributeĀ
in this thing in this open source schoolĀ
rightĀ
and there are lots of careerĀ
opportunities also i'm sure this pointĀ
is very important for you guys yeahĀ
there is lots of career opportunitiesĀ
for this in this fieldĀ
for this language because you know iĀ
told you this is one of the fastestĀ
growing languageĀ
in terms of developers in terms of theĀ
companies using this language you knowĀ
the big giants like youtube curaĀ
instagram google these companies are allĀ
sort of thing just using this languageĀ
python so there are many careerĀ
opportunities and average salary is alsoĀ
high like it's from 8 to 12 per nmĀ
so that is why it is so popular and i'mĀ
sure you are aware about now thisĀ
language some features who are using itĀ
the application areas of python and allĀ
so please make down your own notes ifĀ
you have any doubt you can let me knowĀ
in comment section you can ask me rightĀ
and we'll be using python 3.x the latestĀ
version of 3.x because python two pointĀ
x that version is obsolete now it's noĀ
longer supportedĀ
uh from january 2020.Ā
so they have declared that uh they'llĀ
not support this version now so will youĀ
work on python three point x version theĀ
latest version whatever is thereĀ
so in the next videoĀ
we will seeĀ
history of this language firstĀ
becauseĀ
you know before going to battle betterĀ
know your enemyĀ
so we'll see history of this languageĀ
properly like the inventor of thisĀ
language how whenĀ
why he developed this language why thisĀ
is called as the name python so theseĀ
thing will be discussing in next videoĀ
right so i'll see you in the next videoĀ
till then byeĀ
