Introduction

Are you struggling to make adjustments to your HTML structure using Python? You’re not alone! One common scenario is needing to replace the class attribute in anchor tags (<a>) with href attributes. This task can appear simple at first, but challenges often arise when it comes to implementing it correctly, especially for those new to HTML parsing.

In this post, we'll walk through how to achieve this replacement using a Python script and the BeautifulSoup library, which is excellent for web scraping and HTML manipulation. Let’s dive in!
