Rule-based information extraction is useful for many NLP tasks. Certain types of entities, such as dates or phone numbers have distinct formats that can be recognized by a set of rules without needing to train any model. In this exercise, you will practice using re package for RegEx. The goal is to find phone numbers in a given text.
