Writing a Dictionary to a CSV File in Python: A Step-by-Step Guide

When working with data in Python, you might find yourself needing to export structured information for further analysis or sharing. One common scenario involves writing a dictionary to a CSV file, where each key-value pair is organized into rows and columns for easy readability. For example, consider a scenario where you have a dictionary structured like this:
