How to Properly Loop Through Web Elements Using Selenium in Python

If you're diving into the world of automation and web scraping with Python's Selenium library, you may encounter some common pitfalls, especially when dealing with web elements. One such challenge can be looping through multiple web elements to collect data, such as product names and prices from an online store. In this guide, we’ll walk through a specific problem faced while scraping data and the solution that resolves it.

The Problem Statement

As a beginner in Python and Selenium, you might find yourself facing issues when trying to scrape product details. In this scenario, the problem centered around a script that successfully identified the number of products on a webpage, but the data collected would consistently repeat the first product’s details.

This is the code snippet in question:

The Problem with the Code

The output showed that for all products in the list, only the first product's name and price were being returned repeatedly. This led to an incorrect dictionary filled only with the first product's details:
