The regular expressions processing is supported by many programming languages including python. python's standard library has re module for this purpose. since most of the functions defined in re module work with raw strings, let us first understand what the raw strings are. Regular expressions can contain both special and ordinary characters. most ordinary characters, like 'a', 'a', or '0', are the simplest regular expressions; they simply match themselves. you can concatenate ordinary characters, so last matches the string 'last'. In python, the built in re module provides support for using regex. it allows you to define patterns using special characters like \d for digits, ^ for the beginning of a string and many more. This python code uses regular expressions to search for the word "portal" in the given string and then prints the start and end indices of the matched word within the string.
