How to Convert a Comma-Separated String to List Items in Python: A Simplified Approach

Working with lists in Python often involves various types of data manipulations. One common scenario is converting a string containing comma-separated values into a list of individual items. If you've encountered a situation where you have a comma-separated string embedded in your list, you might wonder how to extract and organize those items into a proper list. In this guide, we’ll address this issue and provide a straightforward solution.

The Problem

Consider this example of a list:

While that method works, it can be cumbersome and may add unnecessary complexity to your code.

The Solution

Instead of using multiple list comprehensions and loops, there's a much simpler way to achieve your goal. You can utilize the join and split methods in Python to efficiently convert the list into a normalized format. Here's the recommended approach:

Step-by-step Breakdown

Join the List: Use ','.join() to create a single string from the list items. This effectively combines all elements, using a comma as a separator.

Split the String: Use .split(',') on the resulting string to create a new list of items.

Here's how you would implement this:
