A Guide to Splitting Inner String Elements in Python Nested Lists

Have you ever found yourself needing to manipulate a list of strings in Python? More specifically, have you wondered how to efficiently split the inner string elements of a nested list? If you've grappled with this problem, you're not alone!

In this post, we will explore a straightforward solution to split each string element within a nested list, allowing you to organize your data cleanly without the elements mixing together. Let's dive into the solution step-by-step.

Understanding the Problem

Imagine you are given a list of greetings as user input. For example:

The Solution

Method Overview

To achieve this task in Python, we can utilize two powerful concepts:

List Comprehension: A concise way to create lists.

List Constructor: A built-in function to convert an iterable (like a string) into a list of its characters.

Step-by-Step Breakdown

Here’s how you can implement the solution:

Original List: Start with your original list of strings.
