Regular expression (regex) is primarily used for string manipulation and filtering, so that you can search and process the strings within a system.

It can get complicated very quickly, and regex requires practice.

Unless you’re working in an environment where you’re always doing string processing, don’t worry too much about it.

If you’re aspiring to be a data engineer, knowing how to use regex is definitely going to be a plus.
