Transcripts

so in the series of learning python

programming language in previous video

we have talked about history of python

language

now

in this video we will install actually

python as well as an ide for writing

programs in python language and then we

write a simple program just to print

hello world that's we usually do

whenever we you learn any programming

language first program you write is

print hello world so this these three

things we'll do in this video right

python is a interpreted language so that

is you can say basically we will you

know install the base interpreter for

python

right so now let's see how to

install these things one by one step by

step

okay

first we will search like

just

write down download python

okay

and

better

to open the website

the website of this python dot or

python.org

right

and here in the download section you

will find download python 3.10.6

the latest version is 3.10.6 so we are

going to download this version for

windows

okay so just click on download and

that's it

it will take only few seconds and see

it's been downloaded let's just click on

this

and now

how to install this you can click on

install now two options are there or

customize installation in customize you

can choose your location and some

features

right by default this would be your

location if you click on install now

okay it will include ideally pip

documentation and all we'll see what is

ideally what is pip basically to install

python packages and all you'll see one

by one these videos but for now just add

this uh

just check this also this textbook

checkbox add python

3.10 to path means

automatically it will be added to path

and directly from cmd command prompt you

can

run the center better you can run the

commands on python you don't need to add

any path right so i'll do customized

installation okay see in this what are

the features documentation pip it will

install you know pip which will download

and install python packages

later we will install some packages also

in python so using pip we can do that

thing

okay

now

let's let's click on

next and install for all users right

and you just keep everything as it is

this is the location install location c

program files and python 3.10 okay and

click on install that's it and then

yes

now it has been started and it will take

few seconds to install this uh language

to this this interpreter for this

language here we are downloading the

base interpreter for python

right

now after that we will install ide

pycharm basically id is one integrated

development environment

which is basically an application or you

can see it's a software to build

applications it is having text editor

also code editor

okay with there you can write down code

uh with having some syntax like syntax

highlighting some extra features it is

having syntax highlighting

autocompletion if there is an there is

any error then underline it will show

red underline

under that line in which

you are having error same as we have

installed and we have worked right now

also we are currently working visual

studio code uh when we were we run c

plus plus program so for this that id is

an id also having compiler debugger

right many things in simple and in one

software we are having many things so

that is why we use id

rather than writing our programs in

notepad we generally prefer ids many ids

are there so here we use pycharm so

after this we will install pycharm okay

now let's just uh click on this end

download

pi

cha

okay

it is by jetbrains

so you see the first website only

jetbrains.com

right

it is by jetbrain so just

click on that thing and you will find

two version here

professional as well as community but

better to download community version

because it would be paid it would be

free for it it is professional is a free

30 days trial only

so we will

download community version okay

it has been started

now as you can see

our setup is also going on and we have

so now python 3.10.6 64-bit setup is

successful we will close this

see as you can see also there are

various releases previous release 3.10

3.9 3.8 whatever version you want to

download you can download

right

but better to download the latest

version that would be fine

so as you can see these are the versions

you can download other than this version

3.9.6 you can download any other version

also it's up to you

right

but better to download three point x

version only know two point x because

they have

added the support for two point x

version right now how to check that we

have successfully downloaded this python

so just

you can just uh click on this you can uh

open your command prompt cmd type cmd

and this is your command prompt right

now here i will

write

python

version

hyphen hyphen version so see it is

showing me the version 3.10.6 yes it has

successfully

downloaded and installed sorry why not

download it install this python this

interpreter for us

right

so if you

enter

write python and enter then our this

interpreter for us has been started here

you can

you can use this thing for calculate as

a calculator or you can write down your

commands here

you can do programming also here line by

line

so see if i write 3 plus 2 it will show

me 5

so this can also be used as a calculator

so line by line because interpreter

would do what integrate line by line not

the complete code so only one line you

will write and it will show you the

result of that line so simply we will

exit

from here simply type exit and

press enter

and one more thing we have also included

we have also installed pip that was used

to install some packages and all if you

want to check that thing also you can

just

write down pip here and just

enter so see it will show you something

like this the result

after

uh clicking

after writing pip and clicking just

enter

so this would be the case so means uh

tip has also been installed successfully

you don't need to do anything loud now

they just close it

now we will install our python the ide

so let's click on this the community

version that we have downloaded already

and it will show

this screen just click on yes

and next

and this is the destination folder for

our

this

installation then click on next

simply click on next or you can write

down

create if you want to create desktop

shortcut you can just click on this

open folder as project this also you can

click if you want to add bin folder to

the path

update path variable

so i don't want to include this thing

you just click on next now

right and simply click on install

that's it it will take some time

right

so it's been done now you can just click

on the run python community edition and

just click on finish

so now it will launch and

just click on don't import settings and

okay right

now it will launch your python community

edition 2022

now what you need to do obviously the

first time so we will create a new

project so click on new project

okay

now see this type of thing would be

there on your screen now what you have

to do

you can just this is your location see

my location is this thing and python

project so if you want to change the

name of your project you can just

i'm

writing first

project

that's it now

new environment it is showing that

virtual environment but we don't need to

this we don't need to do this thing

we need to do what

previously configured

interpreter

for this it was

so now it is showing no interpreter you

have to add interpreter because we have

already installed python interpreter

right so add add local interpreter and

i have which interpreter it's python

3.xc location c user and base

interpreter is program files python 3.10

3010 and python dot exe right this is my

interpreter okay

now

just click on this so if you are you

know if in your laptop it is not showing

anything so you can just click on these

three dots and you can search

you can search in which folder you have

installed in c folder in user or python

in which folder you have installed that

python previously we have installed that

python you just go to that folder click

go to that folder and click on python

dot exe and then select it

right

in my uh pc i have already this thing

python.exe so just click on ok

so it is creating

uh that environment

so see the interpreter is python 3.x

sorry 3.10 okay now see create a main

dot py welcome script it will create a

main dot py the extension for python uh

program says dot p i just say for c we

have dot c for c plus plus we have dot

cpp so same for python we have a dot py

so it will create

a welcome script for s for us right if

you check this if you uncheck this it

will not create anything but i'm going

to check this

okay now let's just create so it is

loading our first project c main dot p

y so it is a sample python script

okay

you can say this

if you want to check out this thing you

can check out otherwise

no it's okay you can

what you can do

you can just

remove all these things and we can do

our simple like we have now installed

our ide so if you want to print hello

world in python how you will print it's

very simple no need to write down any

header file main function and all

one line you need to write down okay now

if you want to write down that thing in

main dot py you can do that thing or

otherwise in first project

you can

you can create you can create a new file

right click on first project new the

name of our project is first project new

and then

file i'm creating new file that is

first

dot

py

here i'll write my code simply you need

to write

print

and

hello world

that's it no semicolon nothing else

nothing else so you can simply

run this

here we have a

you know this kind of thing

hi pycharm so it is

okay it is actually running this main

dot p y this file main dot p y right we

no need to run this file we we need to

write we need to run our first dot py

this file so now let's uh close that

file select this first dot py and sorry

here here not main

you have to select your current file

okay

note main here if there is this kind of

thing you just select

current file and run this

now current file is first dot py so it

is printing hello world on my screen

simple program so i think

with this only you can

identify how much

simpler

is to code in this programming language

python programming language then c and c

plus plus and java and all

to print a simple line hello world you

just need to write down print and that

thing

because it is a string or the string you

can write down in single quote also here

no double quote but actually i am from

that c and c plus background so

i

put string in double quotes and a single

character in single code but in python

you can write down rather than these

double quotes single quotes as well

uh

single quotes

okay let's run this current file and it

will print hello world both are same

single code or double quote it's up to

you

so i guess this is clear to you now from

the next video we are going to start you

know our actual python programming

course we will learn about variables

how to use those data types string and

all

you'll see these kind of things so now

in the next video till then bye bye take

care and if you are finding any

difficulty in downloading and installing

these kind of things you can let me know

in comment section

okay

so let's see the next video now till

then bye take
