Regular expressions, often abbreviated as regex or regexp, are powerful tools used for pattern matching within text. They consist of a sequence of characters that define a search pattern, enabling users to find, replace, or manipulate text efficiently. Regular expressions are widely implemented across various programming languages, including Python, Java, and JavaScript, allowing developers to perform complex text processing tasks. By utilizing metacharacters and specific syntax, regex can match simple strings or more intricate patterns, making it an essential skill for anyone working with text data in computer science, data science, or software development.
