How to Declare a List in Python

In this video, I will explain what is a list data structure and how a list is declared in Python language.

Lists are used to store multiple items in a single variable. Lists are used to store data in a sequential way. In Python, various built-in functions can be utilized for quick data manipulation and analysis. A list is declared within a bracket and it can store an integer, a float, or a string. The elements in a list are separated by a comma.

Here, we have declared three different types of lists. The first list contains integers, the second one contains floats, and the third one contains strings. After declaring these three lists we are printing them with the print command. After executing the print command, you can see the elements of each list being displayed in the terminal.

List items are ordered, changeable, and allow duplicate values. List items are indexed, the first item has an index [0], the second item has an index [1], and so on. When we say that lists are ordered, it means that the items have a defined order, and that order will not change. If you add new items to a list, the new items will be placed at the end of the list. The list is changeable, meaning that we can change, add, and remove items in a list after it has been created.
