A RegEx, or Regular Expression, is a sequence of characters that forms a search pattern. RegEx can be used to check if a string contains the specified search pattern.

22 hours ago · A regular expression (or RE) specifies a set of strings that matches it; the functions in this module let you check if a particular string matches a given regular expression (or if a given regular expression matches a particular string, which comes down to the same thing).

Jul 19, 2022 · In this tutorial, you’ll learn about RegEx and understand various regular expressions. A RegEx is a powerful tool for matching text, based on a pre-defined pattern. It can detect the presence or absence of a text by matching it with a particular pattern, and also can split a pattern into one or more sub-patterns.

Mar 14, 2024 · Regex or Regular Expressions are an important part of Python Programming or any other Programming Language. It is used for searching and even replacing the specified text pattern. In the regular expression, a set of characters together form the search pattern. It is also known as the reg-ex pattern.

In this tutorial, you will learn about regular expressions (RegEx), and use Python's re module to work with RegEx (with the help of examples).

We won't be covering the basics of constructing regular expressions from scratch in this tutorial, instead, we'll focus more on how you can use regex on Python effectively. For a demonstration on how to use re.match() function, say you want to validate user passwords.
