Many Web pages these day are equiped with dynamic content. The dynamic content makes the webpages nicer and neater and enriches user experience with content.
However, this make web scraping a bit more difficult as web scrapers since the content is hidden in the html format. So web scrapers have to simulate a human user rather than a bot in order to correctly get the contents from dynamic webpages. Fortunately there are some packages in python that can perform the job, selenium. If you are using python you can easily install selenium with pip installer. Install pip python.
