#1 Python Tutorial for Beginners | Introduction to
Python

Python is one of the fastest-growing language in what terms in terms of number of
developers who are using it
...
The author of Python he 's a big fan of a
British comedy movie called as Monty Python
...
Python came into picture just to help those people who do n't
know how to read a code in fact children can learn Python is that easy now Python
has multiple versions we have one point X
...

Python 3
...
Python is free so we 'll
be using PyCharm here now is it free that 's the question let 's try
...
You can
verify that is by going to your windows of course and saying hey I want to use
Python now you can see we got a Python zero point seven set up so that we can go
with this one or you already get an IDE called as I dl e where you can also add your
code right
...

PyCharm can be set up for some types of Python files or some extension
...
Click on install and
in some time it will get installed so you can see we got this setup done
...


#3 Python Tutorial for Beginners | Getting Started with
Python

Python is a programming language and a binary format language
...
Python is one of the easiest programming languages in the
world right so what I will do is I would say two plus three this is the
simplest task you can do on Python
...
You can have multiple
operations but then we have to follow grommet right if you say 8 plus 9
and then subtract you forgot to type 10 there it will give you an error
which is invalid syntax and that 's why you need to follow the grammar as
well
...
Problem
starts so what you will do now because if I say enter you got invalid syntax
in that case we will say single quote navin's and then in double quotes will
say laptop
...


In this video we have only talked about how can we use certain operators
and then playing with printf in the next video we are going to talk about
how to use variables now
...
I hope you enjoyed this video so click on the like
button and do subscribe the channel for further videos
...
What is variable so
basically variable is a container where you can put your values
...
In
assignment what we do is we have a variable name equal to our value so
we are assigning to to X
...
YouTube is a string of
characters that means even if I want to fetch one character it should be
paper we should be able to do that right and yes we can do that
...

If I specify only one and colon if I do n't specify ending what happens in
this case it will start with 1 and it will come it will go till the end okay that
has well so if you don't specify the ending part it will end at the last one
which is available so it will not give you any other
...


#5 Python Tutorial for Beginners | List in Python

Ivan jetty shows how to work with variables in Python
...
The list is a list of numbers, strings and
numbers
...
Negative numbers can be used in C C C++ Java
...
Python is already thinking about Python this is we have so we have a list
where you can have different types of different types
...
List is mutable or what is that new table simply means you can change
the values and we can do that here nums dot append append I want to append I
what I
...

Python has this amazing documentation online so just need to go to online and
search for Python Docs you will get the documents in the next video we are going
to talk about how to use the help command which is very useful actually so we 'll
see that so if you want to add multiple values just wait to read it of course you 're
watching this video
...
type nums dot extend and in
the bracket specify multiple values if you want example
...
The series
is a series of videos on Python
...
So when we learned about laser it 's very simple right
...
in certain projects
...
I do
n't want to change it so of course you will go for a tuples
...
If you want to enhance the
speed of your execution
...
We want to fetch the element as fast as possible, so it
simply says okay just
...
set is almost same as list
...
It will not
maintain the sequence and will not support duplicate values
...
We we need the command right so here if I say Python if I
...
It says Python is not recognized that 's weird that's bad about this right
How that make it work what 's wrong here the thing is
...
the best way to check Python is by using print, Hello World print and Hello
World Center It works right
...
This is how you set the part if
you are if you want to access Python in your machine okay that 's great now once
you have talked about this we have nothing to talk about is help
...
you should be
watching my videos and then with my videos you can read the documentation right
it will be really
...
so if you? If you scroll down, we have some methods here
which we have used
...
So it talks about everything so which version has been included which
things and this is amazing
...
He explains
how you can practice the entire Python code session which we have done
...
the software is
free, but you can actually use it for free
...
if you
want to execute Python How will I do that it 's very simple simply type Python code
...
You can run the code simply say control B and you can see it in the
bottom section you got a loop world
...


#9 Python Tutorial for Beginners | More on Variables
in Python

Devin [UNK] "let's cut it up this series on Python and in this video we 're going to
talk about variable
...
We know
how to get variables how to assign values and you can change the value as well
...
we 'll talk about more about memory consumption and
what happens when you create multiple variables
...
in Python
...
They will not be getting
multiple or the multiple boxes for for each variable
...
We can also
do that
...
I can we 'll talk
about that later how it works
...
Later
...
You know we have P A VM or chase garbage collection, so we
talked about those things in detail
...

C programming is the only place where you can make a variable constant right, but
in Python you can not do that
...
This is
the constant
...
can I create my own types and we 'll be doing that later
...


#10 Python Tutorial for Beginners | Data Types in
Python

720 is 720 and let 's continue this series of Python and in this video we 'll talk about
one of my favorite topic which is called as data types
...
The third one is least double set string range and map
electron coitus Dictionary
...
Example, our value
which is float and I want to convert that into integer is it possible
...
I will take a variable called as a and the value in a I will assign as five
point six
...
It 's very simple just use a complex
function at the way we are doing and then you can pass two variables here
...
Python has worked with lynch before right so
...
Comma 6
...
comma 45
...
Comma 12
...
You can take string as a matter
...
If you are creating a string let 's say I will say this is st is equal to and if you
have a single digit or single character that's a guy type for you, but actually it is
string
...
Example
...
what we can do is
...
So what I
will do is
...
In fact there is another way of
doing this
...
every mobile phone has a name or a key attached to it, so it will be easier for
you to fetch right okay now it 's not just about string Okay
...
we can use a key which is your name and a value to identify each object
with a key, How do I do that
...
In fact, we have one
more way of fetching value instead of using a square bracket
...
You can mention hey I want to fetch let 's say killins
phone which is wonders right
...
In this video we 'll talk
about automatic operators, assignment operators, relational operators and logical
operators and we have one obvious unary operator
...
In fact, we have tons of one of the thing before right in
one of this one of our video, where we can compare two numbers or we can even
compare two stuff so smaller great or compel equal to so let 's try here so there
again we 'll go for two variables here which is a and b, which we've done before
and of course the value of a is five
...
When you use this angular symbol, it 's
less than we can also use greater than symbol right now what if the value of a and

B of course they are not same so how do you check for these say comparison if
they are same in because if we can not use single or single equal to means you are
assigning it
...

The next set we have is logical operators so before understanding what logical
operators are you to understand the concept of true and false and relation between
So
...
The first
condition is true right and second is false because B is not less than 2
...
The resultant condition will also be true right so if both
events are true, then only you will get true that's the property of and so the same
thing can be done for all
...
This is how your all-to table looks
like
...
We'll talk
about different number systems
...
In in normal system, we use decimal system
...
Where we have eight digits
...
On
the other hand, we have 16 as a base
...
Now everyone knows right so it is 2 into 12
...
how do we read this so we have to start from
...
Then we have this is 1 0 0 1
...

This is a binary format of 25
...

We will be working with different operators like bitwise operator
...
try to find the panel format of lecture 31 then try to find out
bunny format of 21, then 52 then 65
...
Take the start on
the last number and use two days to zero
...
number
...


#13 Python Tutorial for Beginners | Swap 2 Variables in
Python

Python shows how do you swap two numbers in Python using a third variable to
swap numbers
...
So it is not
exactly swapping it now What's happening here The thing is the moment you say a
equal to B
...
value for
...
We wanted 5
...
We can use operators like +-or you can use this cap symbol which is [UNK]
symbol now Excel works on different way so what you can do is
...
When
you say B is equal to a right so normally
...
THe
value for B is 6
...
THis goes into stack, so we have a stack
...


#14 Python Tutorial for Beginners | IDLE Previous
Command | Clear Screen?

When you say hit enter and if you want to access the same command again, Can
you do it normally? What happens is when you work on CmD what we 'd get is
...
This is not a command
in windows, but we do n't have by default option
...
do that is by closing idea in reopen it okay now if you have seen my
videos in my videos
...
I made
sure that it goes up so that you can view it so I have not scrolled on idla so as for
my knowledge, it is not possible
...


#15 Python Tutorial for Beginners | Python BitWise
Operators

Ivan 20 is Ivan 20's new series on Python
...
this time we have six different
operators
...
Let 's talk the first one
...
This is
what they will teach you in the first year, but if you have if you don't know this
concept that 's okay you can learn here now
...
We can use bitwise and and bitwise all so in and remember this
thing
...
remember this table right that 's what you 're going to do here Now so
let 's do bitwise' and now which operator we use here are a and D and is for logical
operations
...

Since we do n't have any one here we will get 0, then you have 0 1
...
If form do remember in a shortcut way
...
left shift operators are left shift operators which is another lefthand
side
...
in left shift
...
You're losing bits that's what you find
...
It 's very si mple so we
also have a positive right shift right
...
consider this one so this is
32 and this is 8
...


#16 Python Tutorial for Beginners | Import Math
Functions in Python

Devin [UNK] in Python, we have a lot of modules to work with now
...
If you want to use them, you need to ask for it
right
...

flow will always give a last the least value and c it will give you the highest value
highest integer
...
We also have power you

know p or w
...
As m
...
We can also get the
value of epsilon
...
In fact, we 'll
search here
...


#17 Python Tutorial for Beginners | Working with
PyCharm | Run | Debug | Trace | py file

##NK] "let 's get rid of this series on Python
...
Now It 's
time to do something big no when I say big I 'm not talking about making games
or something because it takes time okay
...
how do you learn this file just go here on run
and click on run module
...
There are multiple ways,
but this is one way
...
You can store it anywhere
you want, But is it easy to access will be desktop so I will go to desktop
...
can write a code
...
all the codes work on
every code that works on all the ideas now, how do we work with my charm
...
Neal explains how to create a breakpoint and how to run the code where you
can debug the code
...
you can crack
what is happening in fact on the on the here itself you can you can see record X
[UNK] 5 [UNK] 5
...
wrong between line
number 20 and 15 but well so you can trace you know you can play put a
breakpoint
...
He explains how
a pencil should notify user hey user
...
[UNK] "
...
I will say here user enter
the value so of course, it 's not compulsory" when you want to work with a function
called as input
...
The problem is what is happening here is if you have observed
...
This time
at least we 'll be getting 14 right
...
will work on IdL editor, as
well as IdL editor as well
...
This time I
will go for some other values
...
It should give you 10 and it works
so this thing is working now in fact the same code
...
There is also a concept of fun,
so you just play with it
...
In fact,
since we are working with input, we can do something extra
...
to pass a value from here
...
if you want
to access a particular value, you need to use index number
...
So if I go back to my command round
...
I
would say Oh
...
It says a RGB is not defined
...
Python is the
latest episode
...
Please share your knowledge of the
series and videos with us at the end of this week's episode
