In Python, a list is a collection of items that are ordered, changeable, and allow duplicate values. Lists are created using square brackets and can contain items of any data type¹.

Creating a List

You can create a list by placing elements inside square brackets [], separated by commas. Here's an example of creating a list with three integer elements:

Accessing List Elements

List items are indexed with the first item having an index of [0]. You can access list elements using these indices. For example:

Adding Elements to a List

You can add elements to a list using methods like append(), insert(), and extend()².

• Using append(): fruits = ['apple', 'banana', 'cherry'] fruits.append('orange') print(fruits) # Output: ['apple', 'banana', 'cherry', 'orange']

• Using insert(): fruits.insert(1, 'blueberry') print(fruits) # Output: ['apple', 'blueberry', 'banana', 'cherry', 'orange']

• Using extend(): more_fruits = ['pineapple', 'mango'] fruits.extend(more_fruits) print(fruits) # Output: ['apple', 'blueberry', 'banana', 'cherry', 'orange', 'pineapple', 'mango']
