Lists are used to store multiple items in a single variable. Lists are one of 4 built-in data types in Python used to store collections of data, the other 3 are Tuple, Set, and Dictionary, all with different qualities and usage. Lists are created using square brackets: Create a List: List items are ordered, changeable, and allow duplicate values.

Lists are created using square brackets : Python lists come with several built-in algorithms (called methods), to perform common operations like appending, sorting, and more. Append one element to the list, and sort the list ascending: Sometimes we want to perform actions that are not built into Python. Then we can create our own algorithms.

Python uses the square brackets () to indicate a list. The following shows an empty list: Typically, a list contains one or more items. To separate two items, you use a comma (,). For example: Since a list often contains many items, it’s a good practice to name it using plural nouns e.g., numbers, colors, and shopping_carts.

Python provides a variety of built-in methods to manipulate lists, including append(), extend(), insert(), remove(), pop(), index(), count(), sort(), and reverse(). By understanding these methods and how they can be used, developers can more efficiently work with lists and build more powerful Python applications.
