Web scraping can be as simple as copy-pasting lines of song lyrics, but web scraping that organizations use to harvest large scale data is an automated process. This automated process can be complicated, with all the legalities around copying and available online data forms.
Python tools are available to help automate harvesting data and point users to the content they are looking for on different websites. There are several python web scraper tools in the market today, both for programmers and non-developers. But first, what is a web scraper?
