Troubleshooting Your BeautifulSoup4 Web Scraper: How to Get All Results

Are you struggling to get multiple items from your web scraping script using BeautifulSoup4? If so, you're not alone! Many developers encounter this issue while learning web parsing with Python. In this guide, we'll explore a common problem and walk through a solution that will help you retrieve multiple results from a web page.

The Problem

You created a Python script that uses BeautifulSoup4 to scrape items from a particular web page. However, to your surprise, the script only returns one item, leaving you with incomplete results. Frustrating, right? You might be wondering what went wrong. Let's break down the issue.

What Went Wrong?

The fundamental problem lies in the definition of your search parameters:

The code specifically looks for a section with the class search-results-page__user-ad-collection. Unfortunately, there is only one instance of this element on the page, which is why your script returns only one item.

The Solution

To collect all items from the list of ads, you need to refine your approach. Instead of targeting a single section, we're going to look for each ad's div and extract the relevant information from there. Below are the steps to modify your script accordingly.

Step-by-Step Changes

Modify the Target for Items:

Instead of looking for a single section, we'll look for all relevant a tags that represent each ad.

Updating the Code:

Use the following revised code, which includes these changes:
