so this is the first lecture of our

python code so you can say python course

we will see in this video introduction

to python right

like you can say some features of this

language application areas who are using

this python why this is so popular

nowadays some features this kind of

thing we'll be discussing in this video

about python or python

i'll pronounce it as python right okay

now see python is nowadays the most

popular programming language but you can

say it is the fastest growing

programming language nowadays it's not

like that it is new language because you

you know you think that

recently it is it has become so popular

so it is a

new language no

the concept of python came into picture

in 1989

and even java

was you know the concept of java or came

into picture in 1995 so it is before

java

right but

recently in past few years like

python has become so much popular and

why so that also will discuss

right now basically in every area python

is being used right now the main areas

are machine learning data science

artificial intelligence see nowadays the

data is a big problem many companies

like you can say your facebook

youtube any shopping websites

they are having

data of billions of users right and how

they manage that data

and one more thing is what see i think

you have noticed

if you suppose uh

nowadays i

you know a search for especially chicken

carry kurtas

right

so

i have i've been looking for these

kurtas on two or three website shopping

websites and whenever i open any other

website you know for study

that kind of thing

so

those relevant ads they show me

now ads of those chicken curry kurtas

and all so have they come to know the

advertisers like how they come to know

that i'm interested in buying those

chicken curry kurtas

so this is what they have analyzed my

data

how

many websites i have visited in which

how you know i'm interested so they have

analyzed that data they have collected

my data they have analyzed that data and

according to that they have mind you can

say some

pattern they have formed

and they come to they come to know that

i am interested in chicken keri kurta so

they show me the relevant ad

i think you must have noticed this thing

also

right

so this task is what this analysis of

data and all

in this also python is being used

right

so

in many areas this is one application of

this language and see in many areas like

whether it's software development it's

web development software testing machine

learning artificial intelligence data

science game development making of any

apps mobile apps desktop app websites or

web apps anything hacking even hacking

in many areas

right now python is being used and it's

not like that small companies are using

this language no the big giants

companies are using this language maybe

the main language or supportive type of

language as a support language

you can select like google uh youtube

cura instagram these companies are using

these big giants are using this language

right

and the person who are using it

researchers scientists

software developers software engineers

software testers game developers

mainly

data analyst

and even school going kids

they are also

learning or you can see using this

language

see

because

you know researchers and scientists they

want us

like they don't want to you know uh

utilize or you can say wasted their time

by learning a complicated language and

python is easy language so they talk

they

went for this language python language

so that is why recently this this field

is a you know on boom machine learning

artificial intelligence data science

this kind of thing so that is why with

that field python came into picture

because they these kind of people

researchers scientists so they are

working in this field they want a simple

language to work on right they don't

want to waste their time on learning a

complicated type of language python is

very simple very easy to understand

language so they took it for this

language and that is why this uh

language has become so much popular

within the you know recent years so

white has become so popular because

first thing is it is easy to learn easy

to understand and it has wide range of

applications i have told you in how many

areas almost in every area

it's been used

second thing

you can write down you can solve any

problem with

fewer lines of code suppose you want to

print hello world in c language

so that those header files main function

and printf hello one in c plus plus also

header files std name space std main

function and all in java

those you can say the main function

system uh sorry public static void mean

then system dot outdoor printer and then

hello world this kind of thing in

python simply what you need to write

print

hello world

that's it

nothing else a simple line

nothing else

so

in fewer lines of code you can solve

complex problems

right and more easily you can understand

this course so it will

you know save your time also

another benefit and it is high level

language you don't need to be aware

about those memory management type of

thing like in c you have to aware you

have to you know keep track of you have

to manage the memory manually but here

automatic memory management is there it

is high level language so you can do

more

with

less

right with the writing you can say less

code you can do more in this it is

object-oriented programming language but

it's not like that it doesn't support

that paradigm procedural and functional

it supports multiple paradigms

object-oriented procedural as well as

functional

right it is multi-paradigm language it

is general purpose language almost in

every field

for making everything you can use this

language

it's multi-purpose language

it is

interpreted language these are some

features of python you can just note

down these features so it is also python

is interpreted language without compiled

language

right

and one more feature of this it is open

source right so that is why it is having

a huge community and rich library many

ill

you know inbuilt packages modules

functions those

you can use in your program without

writing those functions from scratch

because it is open source anyone can

contribute

in this right they can write down their

packages or functions or modules and

they can contribute it is open source

anyone can use

those inbuilt functions libraries and

all

right like in cnc plus

also we have some libraries in there

predefined functions are there these are

already defined function like uh if

for string concatenation we use directly

a function str tap so the definition of

that function is already in those

libraries you don't have to write down

the definition of that function you

don't have to tell the compiler you just

use that header file string dot h and

you can call that function because it is

already been defined in the library by

some

other people so by someone else

so same

it is also having rich library because

it is open source so

and huge community it is having if you

are finding any difficulty in this

so there are many forums discussion

forums you can post your queries and

definitely you will get answer for

example some libraries are you can say

numpy pandas tensorflow for machine

learning and data science while in this

field they use that library see

basically libraries are what

some codes are written codes so for some

basic functions are written on those

libraries so that programmers don't have

to write down those function from

scratch and they can reuse those

functions in their own program right so

that

obviously it will save time of any

programmer right because they are using

they are reusing that function

like for making chapatis you need atta

right so just go to any shop maybe you

can buy whole wheat or

atta right but the process behind that

thing generally farmers do that process

that long process

right they have done for you

so they have built those things for you

you just have to go and buy you can

reuse that you don't have to do the

whole process from scratch because it

will take definitely long time

and you don't know definitely most of

you don't know how to

do that farming process

so same thing those inbuilt libraries

packages modules functions are there

programmers can reuse those functions

and so it saves the time of programmers

and many frameworks are also there like

django flash

if you are interested in web development

right

and i told you like automatic memory

management is there in this language

right and it is extensible language

right you can extend you can support

more features can be supported you know

can be added like more libraries or

functions can be added because it is

open source anyone can contribute

in this thing in this open source school

right

and there are lots of career

opportunities also i'm sure this point

is very important for you guys yeah

there is lots of career opportunities

for this in this field

for this language because you know i

told you this is one of the fastest

growing language

in terms of developers in terms of the

companies using this language you know

the big giants like youtube cura

instagram google these companies are all

sort of thing just using this language

python so there are many career

opportunities and average salary is also

high like it's from 8 to 12 per nm

so that is why it is so popular and i'm

sure you are aware about now this

language some features who are using it

the application areas of python and all

so please make down your own notes if

you have any doubt you can let me know

in comment section you can ask me right

and we'll be using python 3.x the latest

version of 3.x because python two point

x that version is obsolete now it's no

longer supported

uh from january 2020.

so they have declared that uh they'll

not support this version now so will you

work on python three point x version the

latest version whatever is there

so in the next video

we will see

history of this language first

because

you know before going to battle better

know your enemy

so we'll see history of this language

properly like the inventor of this

language how when

why he developed this language why this

is called as the name python so these

thing will be discussing in next video

right so i'll see you in the next video

till then bye
