You will be using them throughout your programming career. Replace all occurrences of “NYC” with “New York City”. With a regular expression, you can do the same find-and-replace action but catch “N. NY, NY”, “nyc” and any other slight variations in spelling and capitalizations, all in one go. That’s the least you can do with a regular expression. Likewise, they are extremely powerful for data cleaning. Regexes involve a new syntax to memorize.
