Transcripts

Welcome to 100 days of code guys

In 100 days of code, we are going to learn Python programming

From zero to job ready

Which means here if you gave your 100 days

Dedicated 100 days

So in byte sized lesson I will tell you

Python programming

We will take it from 0 to advance

In start you will feel that,

It is so easy.

Python is a kid's game.

And after that as videos will move forward

We will go up to day 100.

We will raise the bar like anything

We will be working on complex projects

We will be working on things that are used in industry

So too much of excitement and fun is gonna happen.

Python is a dynamically typed

Object oriented programming language

Which was made by Guido van Russom in 1991

Guido van Russom

was watching a show named Monty Python's Circus

On TV when he was working on this language.

And he thought why not name it as Python.

And since then its name is Python

In this course, along with theory

We will do lot of practice,

Many exercises and quizzes are going to come in this.

And many challenges are waiting for you guys.

So I will enter on my computer button

And I will introduce you to different and unique Python.

So like this video right now,

And by subscribing turn on the notification.

So that you don't miss any day.

And everyday you receive notification

Because it is very easy to get lost in sea of YouTube.

So everyone accept the 100 days code challenge.

And in comment section write

I accept 100 days of code challenge.

So, here I am on this google chrome browser

And I will tell you guys

How to download and install Python.

So as you will write Python

Then you will come to python.org

And as per your platform

You will get the latest version available for download

So you can see I am on mac os.

So for mac owners 3.11

It is giving that, so I will download it.

until it is downloading

You can download any of your favorite ide or vs code.

To use Python in your computer

But here I will use Replit

And you guys can use replit

This is a collaborative browser based IDE.

I am using this because,

Because I find it easy to use,

And along with that,

It is easy for me to share code with you guys

So here I will sign in with my google account.

And after that I will be redirected to the screen.

So as you can see all my repl's are over here

Replit basically gives you an online way of writing code.

If your computer is not fast

Or if you have problem compute wise

Which means if your computer lags a lot,

Then you just need a browser tab.

And you can follow with me.

And because I will use replit

It will be easy for you guys to follow me.

So quickly, over here I will go on myrepls

Here I have already made some repls

And by scrolling below,

I will go to Python zero to job ready folder

And this is the day 1 repl ok.

so here as you can see,

You can see my video here in floating pane.

And here will be my content.

And here I will write code.

So I will write the console over here.

Along with that the code I will show you,

I will close this over here,

I will write code,

And here we are going to get the output of the code.

So quickly I will make a file over here,

So I will click here and open main.py

Actually I want to main.py over here .

So look how easy it is to use.

Here will be tutorial.

Here we will write code.

Here there is going to be the output.

And here will be my video.

Which you can watch.

Now, here I have added a demo video.

Here you will get to see the day video.

If you are thinking how I did it,

So I will give a link in description,

You will get to know how to do this thing.

In case, if any teacher is watching this

Now, lets quickly talk about Python.

But before that,

I would like to talk , what is programming?

As you can see,

Programming is a way to tell computers what to do?

We are trying to tell computers,

What to do? And we do it with the help of programming.

If there is a calculator in your house

So calculator is programmed

In such a way, that we can tell it

How much is 5+9

Now, you will say 5+9 is 14.

If I know, then why should I use calculator

But how about 23453453 * 56456

You can calculate it,

But you can't be as fast as computer.

So in such situations a good communication with computer

Is very important

So we use programming.

In the way you and me talk in hindi

You talk with your friend in English.

You must be talking in spanish

Or if you must be talking in any other language,

To talk with computer

We use programming languages.

Like Python, c,c++,java

There are many more programming languages in market

But this course is going to be dedicated to Python.

And this is because Python is very easy.

According to me Python

Is the easiest learned programming language.

Because when you learn Python

After that you start doing things,

Then you have fun at a different level.

What is Python? Dynamically typed.

General purpose programming language

Which support object oriented paradigm

It also supports functional approach.

If you don't know what is this?

So we are going to learn it in this course.

Now, it is interpreted.

It is a high level programming language.

And Guido van Russom started working on it in 1989

Many people ask

When was Python developed.

So it was not one day or one year

From 1989 over the period of years

Guido van rossum created it.

So many places you can see 1991

And some places you may see 1992

You also get to see 1989.

But the truth is from 1989

Over the period of years it was made.

What are the features of Python?

First thing that I will tell you

It is simple. It is the most simple programming language.

This is the best feature of Python which I like.

And after that you can do anything with it.

Platform is independent.

Platform is independent and

It means that,

If you wrote code in windows

Then you can run it on linux too.

And if you wrote code in mac

Then you can run it in windows too.

You can run it on any platform.

I am writing code here in my browser.

Max able means I am using the replit platform

But even if I write code in mac

Then too it was easy for you to run it anywhere for you guys.

It is an open source programming language.

Most important thing, you don't need to pay to use Python.

Which is amazing.

And Python provides very big library support.

So many people use this easy language.

Because of this what happens?

All people are working on some or the other project.

And the project of all those people

The code written by them

They effort written by them

Maybe somebody made one thing in 1 year

And you get to use it for 1 min

It is a very nice thing.

If I talk about learning point of view.

If I talk with error point of view

Maybe the error you are getting today

10 years ago maybe someone got the same

And he may have found code for it.

And has added to website like stackoverflow

It will be very easy for you guys.

It will be very easy for you get solution of that problem.

Ok, Python works on a big library support.

And after that integrating it with other programming languages

Is very easy.

It can be linked very easily to any language.

After that this has some applications

Which I have written over here

you can work on database too.

You can work on data science.

You can work on machine learning.

You can make web applications.

With database

Many serious and complex application can be made.

And to increase your business

Many complex mathematical operations

You can do with the help of Python.

Now, here I am using replit because

Sharing code is very easy.

Installing Python in local is also very easy.

Simply on any platform

Simply you can install it.

Just like some game.

And if you are on mac

It is easy installation as you can see on computer screen.

But if you are on windows

So by installing Python

Just pay attention to one thing

If you are installing in your computer

Path variable @Python 3. which ever version it is

There is option as path

Definitely check it.

Because if you don't check it

So maybe you won't be able to use Python through terminal.

So if I open my terminal

If you are on windows or anywhere

Here I will write Python

So look here it is written that

Python not found.

So we need to solve this problem too.

If you are in linux or mac like me

So if you will write Python

Then you will definitely get to see this error.

So if you will write Python 3,

Then here you can see Python repl

Repl's full form is Read-Evaluate-Print Loop

And here you can use Python as a calculator.

You can run commands like this.

If you don't know what is this print statement

Then we are going to learn.

Over the period of days we are going to learn.

Day by day, slowly slowly I want you to digest things.

So if you want to come out of repl

If you want to come out of this read evaluate print loop

Then do exit

And you will come out.

But do you what I am going to do?

I am going to use replit.

And inside replit, all the file and

Project we make is called repl by replit.

And this repl name has arrived from here only.

Read-Evaluate-Print Loop of Python

Or in many programming languages it is there

From there this is derived.

So here if I write hello world,

And after that if I click on run,

So look it is this easy to work with.

I would like to see its output over here.

And why has the output not arrived here yet?

It is here, hello world ok.

Now here if I do print 7

Or else 5 and run it over here

Here it will run and after that

I will be able to see 5 over here.

So basically what is happening over here?

I am writing code over here but

But the code is getting executed.

on replit servers.

And I am able to see its output over here.

In this, even if my computer is slow

Then too I can use Python very easily.

And I can make new files also over here.

I can make new files . I can open new files,

And here I can read this text.

And I can watch this video.

I can keep it wherever I want.

Up down front back

And if I don't want to watch the video and do practice

You can make it very small

Very tiny in size

And keep it over here.

Park it over here.

And when you want to watch it increase the size.

So you are going to have a good learning experience.

So I would like to request you guys

The official playlist of Python that I am going to make

100 days of code playlist

Definitely access it.

Like the video and subscribe to the channel

So that you don't miss any day.

The journey of 100 days

In that I don't want you to miss anything.

Access the Python playlist.

Bookmark it and save it.

Next day I will meet you,

In which we will talk about more good things.

And our day 2 is going to be dedicated

On a very interesting and fun thing.

So wait for day2.

And we will meet after that.

This much only for this video guys.

Thank you so much guys for watching this video.

And I will see you next time.
