Mastering Web Scraping with Beautiful Soup: Extracting Bank Details Easily

Web scraping is a powerful technique utilized to extract information from websites. However, it can often be daunting for beginners to get started, especially when dealing with complex HTML structures. In this guide, we will tackle a specific problem: How to scrape the name of a bank, small details, and its corresponding company score using Beautiful Soup in Python.

Understanding the Problem

You might want to collect various details from a financial website, such as:

The name of the bank

The exchange code (e.g., stock symbol)

In this instance, we will use Sustainalytics' ESG ratings page for banks as our target URL. Our goal is to retrieve the essential details from the HTML content efficiently.

Setting Up Your Environment

To begin, you'll need Python installed on your machine along with the Requests and BeautifulSoup4 libraries. You can install the libraries using pip if you haven't done so already:
