Welcome on so today in this video we'll be starting with Python list. So what is a Python list? A list is a data structure in Python that is mutable or you can say it is changeable, ordered sequence of element. So each element or values that is inside of a list is called an item. Just as strings are defined as characters between quotes. Lists are defined by having values between square brackets.

So how we create a list. Whenever we want to create a list, we need to create within a square brackets. So let's say great to use when you want to work with many related values. They enable you to keep data together that belongs together, condense your code and perform the same method and operation on multiple values at once. So when thinking about Python list and other data structure that it type of collection, it is useful to consider all the different collection you have on your computer, your assortment of files, your song playlist, your browser bookmarks, your email, the collection of videos, you can access on the streaming service and more. So to get started, let us first create a list that contains the string data.

So here I'll be creating a list first. So suppose given name of your list first, so I'll give the name as creator. So on the creature, I will store a few items. So as I told you, whenever we'll create a list, we'll use a square bracket and use a square bracket. And inside this, I have to create us string list string data type items. So to create a string data type item, you have to use quotes.

So I'll use quotes here. Shark you C'mon then again, Eva coats and then right squid then right shame when if you need basically whatever name you want to store give you so these are the few names that I want to store in my list. So what I will do is I have created a list and now come in the next line and write, print and give the least name here. So now run it, Shift Enter, we'll run your code and see what you got. This is the output of your list. So as an ordered sequence of elements, each item in the list can be called individually through indexing list are a compound data type made up of a smaller part, and a very flexible because they can have values added, removed or changed.

So in a list, you can add a value, you can remove a value or you can change a value. So lists are very flexible. So lists is also very popular data time in Python. So when you need to store a lot of values or iterate over values, and you want to be able to read, readily modifying those values, you likely want to work with least data type. So whenever you are creating something that you need to change change accordingly or modify accordingly. I prefer to use list or you will also use list because we can change modify add in list very easily.

So now here I've created a string data type list now I'll be creating one more list suppose I given in least one hero create I'll write nothing. And I will just give up air of second bracket and run it what it created. It created a blank list now write type within bracket list one and run it see what it gives, it gives a list so type is a function which will return the data type of the particular element. So I've created a list so it returned a list. Now I'll create one more list suppose list two and give the name list two and within this pair of second bracket and give some numeric values, so when creating a numeric value for a list, you don't need to give right those elements Within codes, you just need to write it with a comma. So one two comma 3456.

So six, up to 6am, creating a list. So run it. And here, just write print list to see it printed the list that you just now created. Now, I will write list three. And here I will write list and appear Of course bracket. What it will do, run it and just write type lists three.

What it does, it created a list again. So this is another way of creating a list. One we can create by using just a pair of square bracket another we can use the function list and give the elements Within this first bracket and it will also create a list. So let me create a list in this way. So list for I'll give the name of the element list for And here I'll write this function first give the pair of first bracket and within this first bracket, give a pair of square bracket, and within this square bracket, write the elements. So I'm just create a numeric data type.

So I write like this way, now Ronnie, here, print list for Okay, now just run it. See, it created the list within the pair of square brackets. So we have learned how to create a list in two different ways. First, we can do by just a pair of square brackets. Second, we can do by using the function list and always I have told you that whenever we use a function, we use a pair of brackets. So here I've used a pair of brackets.

And within this was record after again use the pair of square brackets. So these are the two methods by which we can create a list. Now I'll create one more list called list five. Now within this list five I'll use a just simple method, use a pair of square brackets and using that I create a list. Now within this list type, I only use two data types. One is numeric and there is three.

So one, two is a numeric and a I will use as a string to see what happened here. I'm using both data types. So first two are the numeric values though this this is a string value and then this is, again, the numeric value. So just run it and I'm in right print least five without any error. I got my result. Because list is very flexible.

You can add or you can store different data type in a single list. Here I've stored a string value as well as a numeric value in the list. So it created a list perfectly so in this video you have learned how to create different pleased in two different way so next In the next video we'll be starting with what we can do with list different function how we can use this list in different way how this list work. So till now Goodbye. See you in the next video. Thank you
