Nested lists in Python are a powerful tool that can help you organize and manipulate complex data structures with ease. Whether you’re working on a data analysis project, building a web application, or automating a business process, understanding how to work with nested lists can be a game-changer.

In this article, we’ll dive deep into the world of nested lists, exploring their syntax, use cases, and practical examples to help you become a master of this versatile data structure.

Understanding Nested Lists

A nested list is a list that contains other lists as its elements. This allows you to create a multi-dimensional data structure, where each element of the outer list can be another list. Here’s an example:

nested_list = [
    [1, 2, 3],
    [4, 5, 6],
    [7, 8, 9]
]

In this example, nested_list is a list that contains three other lists, each with three elements.

Accessing Elements in Nested Lists

Accessing elements in a nested list is similar to accessing elements in a regular list, but you need to use an additional…
