Amazon Data Scraping Procedure

For Amazon product data scraping, we will be using Python 3. It's important to note that the code will not run if you are using Python 2.7. You will need a computer with Python 3 and PIP installed.

To perform Amazon scraping, you will must install the following Python packages. You can use the pip3 command to install them:

Requests: This package allows you to make HTTP requests and download the HTML content of Amazon product pages. Install it with the following command: pip3 install requests

SelectorLib: SelectorLib is a Python package that facilitates data extraction using the YAML file generated from the downloaded web pages. Install it with the following command: pip3 install SelectorLib

Use pip3 instead of pip if you are using Python 3.

By installing these packages, you will have the necessary tools to scrape Amazon data effectively.

Use Selectorlib for Markup data fields.

We will create a new file in the same directory as your code and name it selectors.yml.

Open the selectors.yml file and define the data fields you want to extract from the Amazon product pages using YAML syntax. The template should resemble the structure provided in the file.

Save the selectors.yml file.

The markup preview will appear like this.

Selectorlib is a developer-friendly tool that simplifies marking up and extracting data from web pages. It offers a combination of tools that streamline the data extraction process. The Selectorlib Chrome Extension is one of these tools. It allows you to mark the specific data elements you want to extract from web pages. By selecting the desired data elements, the extension automatically generates the corresponding CSS Selectors or XPaths required to extract that data. Additionally, it provides a preview of how the extracted data will look.

Using the Selectorlib Chrome Extension, developers can quickly identify and mark the data elements they need for extraction, saving time and effort in manually identifying and writing CSS Selectors or XPaths. This tool significantly simplifies the data extraction process and enhances the efficiency of web scraping tasks.

The Code

To implement the scraper for Amazon, follow these steps:

Create a folder named "amazon-scraper" in your desired directory.

Copy and paste the Selectorlib YAML template file, which should be named "selectors.yml," into the "amazon-scraper" folder.

Create a new file called "amazon.py" inside the "amazon-scraper" folder.

Copy and paste the provided code into the "amazon.py" file. This code performs the following tasks:

• Reads a list of Amazon product URLs from a file named "urls.txt."
• Scrapes the data from the product pages.
• Saves the extracted data as a JSON Lines file.

Ensure you install the required Python packages, such as Requests and SelectorLib. Once the code is in place, you can run it to scrape the data from the specified Amazon URLs and save it in the desired JSON Lines format.

Now, run the product page data scraper by typing the following command:

After the completion, you will see the complete file with the output.jsonl along with the data.
