Regular expressions

Regular expressions provide a flexible way to search or match (often more complex) string patterns in text. A single expression, commonly called a regex, is a string formed according to the regular expression language. Python’s built-in re module is responsible for applying regular expressions to strings; I’ll give a number of examples of its use here.

Note

The art of writing regular expressions could be a chapter of its own and thus is outside the book’s scope. There are many excellent tutorials and references available on the internet and in other books.
