Simple webscraping project with python 3

Hi there. I work with python and hit the wall scraping a single value from a specific site. The challenge is that the data is dynamic loaded to the site, changing from time to time. I haven´t managed getting the data with the modules selenium, bs4 or/and urllib. I need it done soon as possible. Details about the site will be provided. Requirements: - Chromedriver(headless) - python3 - You can communicate by text in english - Good knowledge about website development (I might have a question or 2 regarding parsing the site)
