For those who do it yourself
This is what a general DIY web scraping process looks like:
Identify the goal website
Gather URLs of the pages where you wish to extract data from
Make a request to those URLs to get the HTML of the page
Use locators to search out the data within the HTML
Save the data in a JSON or CSV file or some other structured format
