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
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
