Python - edit current working script to scrap similary another page(PDF files).

I have a Python script (Scrapy or Selenium, I am up to suggestions) to extract information within some specific websites - daily(auto) or manually. The page is in portuguese, but I will provide a video with the scrapping instructions and the arguments for the function. 1. User arguments: - start date. - final date. - Keywords(can be a list of words) to look for. - User chooses the local path to the files to be downloaded. 2. Back-end: - Access the page. - Searches the tabs that can have useful information(I will provide the specific parts for each webpage to make the queries) links inside that domain. - Download(if the page serves files in doc, html or pdf) and look for the keywords. - Extract all the related content (PDF files or the text in html). - Go around Captchas(if the page has captcha) 3. Logging: - All the extracted content must have the URL which the information/file is available in the webpage - can be done by logs. - All the extracted content must have the DATE which the scrapping has been made - can be done by logs. 4. Configuration: - All key-fields (like CSSSelector for a date field) should be configurable for each spider. - The URL to start scrapping each webpage should be configurable. - If page contains Authentication(Login/Password), user will fill the configuration for it. IMPORTANT: 1. I already have a script working for a webpage. The goal for this project is adapt this script to work similary on another page. 2. I WILL RELEASE THE MILESTONES ONLY AFTER YOU SEND ME THE CODE AND I AM TOTALLY SATISFIED (I WILL RUN TESTS TO CHECK FUNCTIONALITY). 3. MUST BE PYTHON CODE. I have many projects at hand and would be great to stablish a good relation with you, since I constantly need someone to work with me. Thank you.
