Plus learn to track a colored object in a video. Scraping might be fine for projects where only a small amount of data is required, but it can be a really slow process since it is very simple for a server to detect a robot, unless you are rotating over a list of proxies, which can slow the process even more. It is fast and provides completely automated forecasts that can be tuned by hand by data scientists and analysts.
