How to Explode Multiple Columns Containing Strings in Pandas DataFrame
When working with datasets that contain multiple columns of string values, especially when those strings represent lists (like tags), it can be challenging to manipulate and analyze the data effectively. In this guide, we will explore how you can explode selected columns in a Pandas DataFrame that contain comma-separated strings—turning each item into a new, individual row.
The Problem at Hand
Imagine you have the following dataset, which consists of an ID column and two tag columns:

This restructuring is crucial for further analyses, such as counting occurrences or joining datasets. Let’s break down how to achieve this transformation.
The Solution
Follow these step-by-step instructions to explode multiple columns in your DataFrame efficiently.
Step 1: Split the String Values
