Hey everyone soon the last video we have learned the concatenation in the studio we will covering the
marching for that also we need some example dictionary.
And this time we just tightly defined the data types that is being taught.
Data frame
and David going to do the frame and here the values like a dictionary.
And in that one we have a key element that is key.
And for one it's given it has values like One two three then we have another one that is like eight.
And it has value.
Three four similarly be with values like five six seven.
And this is with the seven now copy this whole command C and then come on V change the values if you
want to like eight there.
That's OK.
Now four nine two and one and these two men.
And this one also be keyword.
And now change the indexes.
So right column that is this one see and this one.
Be sure to know if you've been D F one you will get this one and F to disband and this is a little different.
Maybe it's from previous one.
This is deserve to know.
So this is the abridged defunded gay Kevin C. And now merging is very easy even you have to just write
Billy don't much.
There is this index for this one.
And then panties nine panties.
Like the previous one concatenation we require these brackets and in DMV the IDF one and then we do.
But in case of March if you press shift then you will see here that you required the left right.
Both.
So wouldn't it be denoted by hair backwards.
We just required the DFL on the left and left then on the right.
Then we have something.
This is how that we have also learned in joining.
After that we have this on which have some particular key here and then left us by default.
But this required any value that is known as key.
That's where we have taken the column value here.
Now here if you do this thing you will get this.
Here the Bundy F2 and the the how is by default the input.
That is this one.
And here we get it because of Monday.
Now we will get this one same.
And then here we have the own which is again the key.
Fun.
That is the common in both.
You will get disciplined and if you do something like define this key in the last two you
and do the thing you will get the same.
So it doesn't matter what you do.
You have defined this key but if you define both of them in the last like here and let me move this
one you will get them in middle after the first one where you have defined like a B.
Then keep on.
Then you will get the March 1.
Here on this one and if you have more than one keys like if I make another one that is and one more
thing.
If the elements of these are different.
Like here.
If I have four and you tried to do that you will not get that one.
That is the different element there.
And if you do this more like outer you will get this one where the elements for the different one are
and then like in the first one we have four but in DFT we do not have four.
So here we have CND net in India after we have three.
So for three we have the values of Kiki even that is nine and nine but of the Seven are men.
So that's worked for the outer is and if you do the left then only the left key that is for will be
considered right.
Give a lot we consider if you do write you will get only the right key with the element the left key
that is for will not reconsider.
So that's the key here.
And let me make them against him now.
Copy this one.
Come on.
See.
And there we go with this one again.
So come on we know that home just this part.
Come on.
See.
Come on.
And in this one also.
Come on beat and change this one to keep to change the element.
So it will be looked like changed.
Now if you do that one you will get this round.
So that is five two three.
They both Dickies here but this one is here.
So if you have noticed.
So we have just Kiki one that is first accessed or so it was terminated on the third position.
So here on third position after that we have key to this one and this key too for the F two also here.
So why did you not get merged.
Because we did not have passed that one here.
If we want to march the board we have to do something like this one postie back at first and then in
that bracket pass the key to and David go with this one.
