Codename: Web Wizard
As an experienced and versatile web developer, proficient in HTML, JSON, PHP and Python and specifically in web scraping prowess, I am confident that we can make light work of your project. I have successfully automated various complex scraping tasks in the past like your requirement to navigate radio buttons and submitting values before saving the HTML. Moreover, I understand that you're looking to expedite this process without compromising on accuracy or efficiency. I am excited to tell you that this is exactly what my wheelhouse is all about, creating speedy solutions that deliver exceptional results.
While Selenium is a powerful tool for web scraping with a browser-based approach, it can be quite heavy on resources leading to slower speeds. But fret not, I'm intimately familiar with alternative faster methods like using direct call mechanisms such as get, request, cURL, response, and more. Combining these methods with my strong Python expertise will allow us to get the job done swiftly by avoiding unnecessary browser interaction altogether.
Thanks for considering me for your project. If selected, I pledge to provide you with a top-notch solution that saves time without compromising accuracy. Just like the math task at the end of your job pitch: 3 + 2 equals 5! With me on board, your web-scraping needs would be as simple as that with a result that adds up!
