How to Select Specific Div Classes with BeautifulSoup in Python

When it comes to web scraping in Python, BeautifulSoup is a powerful and widely used library. However, correctly selecting the elements you want from a web page can sometimes be tricky. This guide will address a common challenge: how to select only <div> elements with a specific class while ignoring similar classes that contain additional identifiers.

The Problem

You might find yourself in the following scenario: You have a snippet of HTML that includes multiple <div> elements, some with the class "col-16" and others with additional classes, such as "col-16 text" or "col-16 image." The goal is to filter out only those <div> elements with the single class "col-16".

Here is a simplified version of the HTML that you may be working with:

If you try to fetch all the <div> elements simply with:

you will find that it doesn't yield the results you desire. Instead, it's likely returning all <div> elements that match other criteria.

The Solution

To resolve this issue, we suggest filtering the <div> elements by the number of class attributes they contain. Here’s how you can do it step by step:

Step 1: Import BeautifulSoup

First, you need to import the required library:
