All right you know how to slice at least 0 to 1.
We'll give you the first item of the list as you will to do the first and the second item Oldways and
so with Nonpoint race.
You do basically the same thing except with not by race sometimes you have two or more the Nationals
or three.
So let me go ahead and create also with a two dimensional array.
So I'll get that for all these variable.
So this is the number that we'll be working with.
And yet if you want to extract this number here this year this on Alice.
So these four numbers.
Well you'd first need to set the index of the rows that he wants to slice.
So that would be zero to two which you see the first two rows.
Actually we can try that and you'll see that you get the first two rows.
Now if you want all of these for portion here so these two numbers these two you would want to pass
a comb over and over index for the columns which would be 0 1 2 3 2 2 4 maybe you know that's it and
that's it.
And that means you have this indexing system.
So you start from 0 4 rows then row the second row is 1 and 2 and so on four columns the same thing
0 1 2 3 and 4.
And actually if you like you can see the shape of your number right.
So it's 3 by 5 which means 0 2 2 0 2 4.
Great.
And of course you can use the convention or at least indexing.
So you can pass zero and everything off of that or just like that.
So you get all the rows and all the calls from two to three.
Similarly you can get only one value if you like.
Not particularly this one because he is sort of a bonus for x 0 so X is zero is a horizontal axis which
says that there is no rule with index 3.
So we said it's 0 1 2.
So let's pass to there and you get 192 which is the very last.
All right.
More than not binary.
Yeah that's about indexing.
How about iterating through a number right.
Well there are two ways to do that.
The first way is to say let's say for all in your number three percent that will do is it will print
out Varos or fewer not raise.
So what this access is in your number three is the rose.
So each the ration it gets the first row and it prints that out in the first iteration that the second
one and then the third one.
And if you want to iterate through columns you'd want to AXS the transposed version of your number right
and that's how you do it.
And also if you want to reiterate valuably value you'd say four in each dot flat
print I.
So this property what it does is it allows you to AXS value.
So if you're an umpire a one by one and that's about indexing slicing and iterating.
I'll see you in the next election.
