🖥️ How to create a List in Python?

There are several ways to create a new list. In Python programming language, the simplest way to create a list is: to enclose all the items, also known as elements, inside square brackets [] - and separated by commas. It can have any number of items inside, and they may even be of different Data Types - integer, float, string, boolean, or even another nested list, which contains other items of different data types, and so forth.

Let's have a closer look at its syntax, so you can declare your own list. Here is an example, in which you want to store a list of strings. First, Let's declare an empty list - with empty brackets []. Eventually, you will add all of the strings, so that you can store and then access its values, later on.

Empty list
my_list = []

List of integers
my_list = [1, 2, 3]

List of strings
my_list = ['red', 'green', 'blue']

List with mixed data types
my_list = [1, "Hello", 3.4, True, [1, 2, 3]]

A list containing zero items is called an empty list, and you can create one with empty brackets []. But, you can also use the list() constructor to declare a new list in Python, or even convert other data types - like string or tuples, into a list.

Convert string - list
my_list = list('abc')

Convert tuple - list
my_list = list((1, 2, 3))
