    Hello I am looking for a python code to scrape a large number pages and save them as html. In order to get to the page to save, you must click a radio button, submit, and then enter a string of numbers, then submit and then save the html. If the string entered provides an error then you must skip to the next iteration. There is no human verification. I already have a version I made myself that works with Selenium, however I need to increase the speed, so I am looking for someone to see if its possible to do this without even opening a browser and possibly using direct call methods (get, request, cURL, response, JSON?). It should be a simply project for someone who knows how to do this. Please enter the result of 3+2 for your message to be received.
