Keywords

💡Python

Python is a high-level, interpreted programming language known for its readability and versatility. In the video, Python is the main focus as the speaker discusses its installation and usage. The term is used to refer to both the language itself and the software interpreter needed to execute Python code, as seen when the speaker checks for Python installation using the 'python version' command in the command prompt.

💡Interpreter

An interpreter is a type of software that executes programs written in a high-level language. In the context of the video, the Python interpreter is necessary to run Python code line by line. The speaker mentions the interpreter when explaining that writing code in a notepad alone won't produce output, and a Python interpreter is required for that purpose.

💡Code

Code, in the context of programming, refers to the set of instructions a programmer writes to enable a computer to perform a specific task. The video script frequently mentions writing code, such as performing calculations or building software, emphasizing the need for an environment to write, test, and execute code effectively.

💡Software Installation

Software installation is the process of making a software application ready for use on a computer. The video provides a step-by-step guide on how to install the Python interpreter and PyCharm, an Integrated Development Environment (IDE), which are essential for writing and running Python code.

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
