Regular expressions (regex) are sequences of characters that define a search pattern, used to match, find, validate, or replace text within strings. They are widely used by developers, data analysts, and system administrators for tasks like input validation, text parsing, log analysis, and search-and-replace operations across languages such as Python, JavaScript, and PERL. Their compact syntax supports wildcards, character classes, quantifiers, and grouping to express complex matching logic.
