So I think this will we're going to talk about this python variables so frustrating to find whatever
is available is a memory, location and computer memory which holds the value of the value of it.
No, in history.
So it holds some value so that you can just use that value again in your code.
So, again, first of all, let me show you a scenario where we need the variables so we are know country
to do it by seven.
Right?
That is the pie.
So this is the Dujon operator.
And if you type 22 by seven and then you get the value of this.
So what I can do is I can just sit by Ezequiel's to continue to buy.
So now the pie is a variable and it stores the value of 22 by seven.
So this is the assignment operator and we will see the operators in the next year.
So for now we are just storing the value of the version in the variable.
So whenever I take this well, you get prepared because despite will store the value of this one.
So what this value of what is the use of the services?
Whenever you want to find out the area of circular or you want to use this value again, you need to
memorize, uh, this whole value through went on to exit and so on.
So instead you can just slip by.
And if you want to calculate the area of the circle, uh, perhaps you can just say this by instead
of typing this one one four two and you can answer different or you can answer different or as five.
So this is another variable.
And to see what the variable type is, you can just type type of.
Ah, so this file is called integer and distribution for these cultural fruiting points generally in
the small part and the fractional part.
So whenever you see some small patterns, fractional part, it is the floating point, no value and
you can see the normal integer.
It's a no no, it's a..
If you take a type of it will tell me class integer.
So in Python everything is a cross and objects that will be a crisis.
And this crisis represents something.
And these objects are derivatives.
Are those classes.
They represent the exact, uh, syntax, exact members of the class.
So we will see this class and objects in the object oriented programming will have concepts.
So no need to worry about this.
Just, um, keep in mind that this is there is an integer class and this art is the object of this integer,
so that these are store integer values and there is no rule that R can only store the integer where
you can assign it is equal to six point seven.
Now that will be ascending.
So if you come from any previous language, will you need to, uh, declare that the word is equals
to uh, uh, you are two, three, four, etc. right there.
So in other languages, you need to declare the type of this variable to be stored right into R equals
to nine point nine.
So you need nine tonight.
So in today's version, I need to define like this in the other previous languages.
In Python, you can just simply set out is equal to six point seven and it will take the type when it
has been using for type type of hard.
Now going.
So that's our response to it.
So now these are the integer and four defined values.
Now let me multiply by eight into ah into ah so my definition of a star and you get the value Pyaar
Square.
And there is another, uh, uh, the tape that is true.
And there are so many other types of apples and dictionaries, we will see them in a separate videos.
So that means it name so we can assign the string name is going to be.
So whenever I hit the name I that.
You can also print these variables using the print statement.
So you get the priority, all right.
I know what I want to do is I want to see type of name, I want to say that I want this name and this
is a string because this, uh, string is nothing but sequence of characters.
But here we have only one character.
Now, I can also say a name is equal to another.
So I am Nicole.
And now if you don't, then then this whole net will be stored in the name and we also see how to access
only particular elements of the string or the rift in the future videos, that is, we're using this.
So this if I a name, it will be nonsensical.
Now, you can also take this type of name.
It will be string.
So that's about the.
Uh, we have covered the food business and the.
So these variables just hold some value so that you can use these variables separate instead of this
long red number, so that you use other variables you can use anywhere in the code once you assign a
value to them.
So this makes so much easy because we cannot memorize are these values.
We can just say area is equal to two to one by R squared two.
So this value.
So that's how far this video I hope we have understood these variables.
