welcome back aliens my name is a ready
and in this video we'll talk about the
python installation the thing is we have
talked about a language which is very
powerful but then where you will write
your code of course we can simply open
your uh notepad and we can write the
code which we want right so example I
can simply go back here and I can say
okay what type of code I want to write
so it can be anything it can be let's
say 2 + 3 now when you say you want to
write a code it can be a calculation a
computation so basically a normal
calculation like adding two numbers or
deciding in which stock to invest or
maybe deciding who should be the next
CEO so basically the idea is if you want
to write a code to design a software
which can do some activities we have to
write a code but where if you write the
code in the notepad of course you're not
getting the output where do you will get
the output for this uh this is tricky
right and that's why in your machine you
need a python interpreter so basically
we have to install some software and in
this machine I don't have it how do I
verify it's very simple uh you can open
your command prompt so if you're using
Windows you can use command prompt to
check it or if you're using Mac or Linux
uh you can open the terminal so I'm here
on command prompt and here let me see if
I have python now basically the way you
can check that is by saying python
version and if you get this type of
error which which says python was not
found that means in this machine I don't
have python okay with Python 3 you might
also check if do you have Python 3
installed and you can see nothing is
there so even if you have python
installed sometime it will not work with
the python command it might work for the
Python 3 command so do check both the
versions and in this machine I don't
have any so how do you get it so the
first thing we need is python
interpreter and okay let's say we got
python interpreter and then you can
write a code there the thing is in The
Interpreter it provides you an option of
writing a code one line at a time so of
course of course you can add two numbers
but what if you want to build a big big
project now it can be a scientific
project or a AI project now that's what
is booming nowadays so if you want to
build a AI project or a web application
or a desktop application where you will
do it for that you need a software where
you can write the code test your code
run your code debug your code and also
deploy your code to the cloud very well
do it now that's why we have to use
something called an i d which stands for
integrated development environment now
for python we have lot of options now
one is very famous which is your py
charm now this is from jet brains again
in this video I will show you how to
install python interpreter and the py
charm so let's start with The
Interpreter so what you will do is uh in
fact in the updated version of Windows
when you say python enter it will open
the Microsoft store but let's say if you
don't have this configur that's fine uh
what you can do is you can you can just
go to Google and search for python
download so you can say this is the
option you will get so of course the
first website says python you can
download it from here now in the
upcoming videos you might see a
different version of python install and
that's completely fine because in the
version difference you will not find lot
of changes so even those things those
code will work here okay so you can go
for python 3.12 which is the latest
version I feel so if I click on download
so you can see we got download python
3.12 so you can download this version
uh 13 is into preas so don't use 13 as
at this point we got 12 which is 13 3.12
so we can click here and say download
okay so you can see it is downloading
and downloading complete I feel yeah
that's done now depend upon which OS you
have Windows Linux or Mac depend upon
that you can choose from here so you can
say we have different options here and
uh yeah so that's the thing so let me
click on this and install so basically I
don't have this installed so I will just
click here and now this will install the
software okay so you can see we have an
option here which is install now or
customize I will go for simple
installation but before doing that I
also want to say add python.exe to the
path basically even if you have
installed maybe whenever you open a
different folder python may not be
available there so if you do this add a
python.exe to your path you don't have
to manually search for the installation
so you can click on this install now and
it will take some some time now if you
skip that step of add to the path then
you have to manually set the path but
anyway when you do the add to path you
don't have to do the next the other
other steps so by the time it is getting
installed what we can do is we can also
get the py charm downloads done so I
will search for pycharm now pycharm is
from jetbrains which is a very famous
company for the IDS and software tools
so it helps developers now basically you
can also use vs code for python you can
also use anaconda or idla which is the
interpreter and yeah many more so I will
just click on this I will say download
py charm the thing is when you download
or when you get to the py charm it's not
actually free okay now that's a Twist
right so we have two versions there one
is a paid version one is a free version
so I would encourage you to go for the
free version but yes once you become a
professional once you working for a
company then it makes sense to use uh
the paid version so this is the website
and as I mentioned this is developed by
jet brains which is the website here
it's also the company and we also have a
community version so if you want the
community version you can scroll down
and you can see we have two different
versions professional and Community I
will click on the community version if
you go for the professional version you
will get trial for one month so you
decide if you want to use it or not but
I would encourage you to use the
community version so this is getting
downloaded let me go back to my python
setup and looks like python setup is
completed let me click on close so setup
is complete how do I verify again we
have to go to command prompt now one
thing to remember even if you have
installed Python and if you directly do
this it may not work so you have to
reopen your command prompt so now if I
say CMD and let me try now python
version and you can see we got python
installed this time we're getting a
version number we're not getting that
error which was getting earlier so yeah
python is installed now how do I test it
it's very simple you simply say python
it will open The Interpreter now this is
where you can write a code of course
doesn't look good right maybe you need a
software where you will find in fact if
you have learned some other languages
you can write the code you can see the
project you can run the code we'll see
that in py charm but here you can see we
got The Interpreter and here I can
simply add those two numbers and it it
is working right so you can yeah you can
do calculations computations whatever
you can do in this prompt apart from
this if you want to open python you can
also search for python so you can see it
will also give you an app so you can
also use this one this is the ideally
from python in fact ideally looks like
something like this so this is the
python interpreter uh you can also use
ideally yeah I know White theme lot of
people don't like it but for YouTube
videos you know it makes sense to have a
light theme uh it looks good it also
encourages you to learn more but anyway
that's your choice if you want to use a
white or black or dark especially for me
I prefer to use dark theme when I'm
coding and for videos I prefer white
themes anyway that's a different debate
uh so I can just use this I can also say
2+ 3 here I'm not sure if the font is
visible but that's not important if I
say 2+ 3 enter okay we got syntax error
again I will say 2.3 I think I've
entered something weird okay so you can
see we got five there so yeah you can do
this here you can do that here or in the
command prom which we have opened
earlier but what about the pycharm so we
got the pycharm installation done so you
can see we got py Cham download complete
I will click on that taking some time
and if you can see yes okay now setup is
very simple here you just have to say
next next it will detect the python as
well the setup I'll click on next
install again we'll take some time it
looks like a bulky software it is doing
a lot of extraction but that's the thing
with IDs you know they are bulky
otherwise you can also use vs code if
you want that's your personal choice
everything which we are doing in py
charm or on the IDE it will also work on
vs code okay setup complete and I can
also say run here from here or I can
simply click on finish let me open py
charm taking some time
again okay I don't want to import this
settings and import click on okay so
basically I'm using py charm on this
machine for the first time so you will
get some extra prompts okay so what you
can do here is you can create a project
you can name any project you can name
anything you want I can click on Create
and voila you got your project here so
this is how the py charm looks like and
that's your python code again don't get
confused with the code here we'll
understand this one step by step but
this is this is your python code here uh
you can even run this if you want but it
will take some time anyway we are going
to see the py charm how to use it later
in the course so yeah that's it from
this video where we have done the setup
for the python computer and py charm so
if you if you are enjoying this series
make sure that you hit that subscribe
button and also hit the Bell icon
because that's how you will know when I
upload the other videos on the
