I go with my list and I say OK I actually don't need milk anymore but I do need something else I need baking soda perhaps. Well, then I might want to replace the settlement with a new element called baking soda so we can create a variable that will pass and a lesser value. And all I need to do is take my grocery list and reassign the elements at index. In this case, digital marketing company delhi had to be something like again. Baking soda should work fine.

So if I were to print out my grocery list now oops I wanted to copy this. Sure. Although we go and then print off this again. And as you can see my second element is replaced with baking soda. So it's just simple as accessing the index and then re-assigning the value. Similarly, I could actually reassign it to something completely different going to be a sign to a number two or something if he wants it and that's fine that works just doesn't really make sense in this context.

Topic 1:-

Now let's say I wanted to add digital marketing company delhi to my list. OK, there's a couple of ways we can do this. We can append isomers onto the end or we can insert items into the middle. And luckily for us, both operations are actually quite easy. So let's say first of all I want to just stick ice months the end because that's the easiest thing to do let's say Oh no I do actually need milk. I'm going to stick that back onto the end of my list so we can just say grocery list don't spend. 

And inside my brackets here I would put the name of the element I want. I'm just using these real values by the way you can actually create actual variables for these and pass them into the brackets. In this case, maybe I do want to add milk again and I just want to print off my grocery list. See the changes occur. So the milk is stuck onto the end. Now let's say I want to insert something right in the middle of my list so that index to. So index and an x would put it here and shove everything over one.

So maybe I realized I need sugar that we're baking a cake or something so I can simply say grocery list dot inserts and I'll keep in mind the order in which these arguments need to be passed and so first at once and index than at once the object itself. So we'll add in an index. In this case, the digital marketing company delhi to add the objects we want. Is this going to be sugar? So again printing out my new list. Let's take a look at that. And now as you can see sugars inserted Westlock will be before and everything else was moved up by one.

Topic 2:-

Now we've covered so far creating the list we've covered accessing updating appending and searching the last operation we might want to perform is to delete Eisin from the list. And there's again a couple of ways we can do that so we can cool grocery lists dots removed. OK. And now this is going to take in an object as an argument so if we know a specific object exists in this case I realized I no longer need a buzzer.

Found another part of BOCES somewhere then I can simply type in the element Bassa and if it exists within the list we were just going to print out the results as you can see Baso which was the last element here is now no longer in existence in this list. Similarly, I can do the same thing by calling all my grocery list. And actually, the Sorgi that I can call on the delete grocery list and then this time just Palsson an index. So let's say OK run after viewing. No longer need baking soda that is index.

So I'm just going to Palsson this reprint my list. And as you can see baking soda is no longer in our list here. And like above when we got stuff like the length of the tuple and then stuff like the Maxson men absolutely we can do that with a list so it can print my Lanc off a list is OK. And then the actual length so lengths of a grocery list. Similarly, I can do the maximum and minimum max of the list on digital marketing company delhi and men for the list.

Topic 3:-

And I'm just going to replace the length of Paraiso with hoops. This should be the max and then OK. So again just running this is the maximum of my list of sugar makes sense that's a further in the alphabet and the minimum is eggs again the closest to the beginning of the alphabet. There are a few other list operations we may once perform if we want to check any of them out just type in the name of your list dots and then you get this big list of different operations and functions and values that we can retrieve from a specific list.

Otherwise, there's just one more thing I want to cover. With regards to race and that is multi-dimensional arrays so this is essentially a way to store lists within lists or you can think about them as matrices if you want. OK so let's say that I'm creating a monster shopping list so I have not only a grocery list but let's say also I have some clothes that I need to buy. OK. So I'm going to create my master actually create first this digital marketing company delhi list and get to set this equal to another array maybe I need a T-shirt and some shorts and I need some sunglasses. OK.

So I only need clothes and groceries. So I'm going to create a master list and append these two lists together. Well, not quite a pen them together. Rather stick them all into one list. So what you can do is create a master list or it can and maybe more appropriate would be a shopping list. And I'm going to make this a list of my grocery list and clothes list so if I have to then print a shopping list. OK. And run this then as you can see this is now a list within a list.
