Pulling Div Attributes with Beautiful Soup in Python

When working with web data extraction, one common challenge developers face is how to efficiently pull attributes from HTML elements. In this guide, we'll explore a practical solution for extracting div attributes using the powerful library Beautiful Soup in Python. If you are dealing with webpage HTML and you want to gather specific data points stored within div elements, this guide will help you through the process.

The Problem: Extracting Div Attributes

Imagine you have an HTML block with a div that contains various attributes such as data about a vehicle. You want to extract these data attributes and store them in a dictionary for further use, possibly for conversion to JSON format later.

For instance, your HTML might look like this:

Your goal is to extract attributes like data-bodystyle, data-engine, data-model, and several others into a clean and usable structure, typically a Python dictionary.

The Solution: Using Beautiful Soup

Beautiful Soup provides a straightforward way to handle HTML and extract the needed attributes without the mess of string manipulation. The following steps detail how to use Beautiful Soup to achieve this.

Step 1: Install Beautiful Soup

Make sure you have Beautiful Soup installed in your Python environment. You can install it via pip if you haven't already:
