What is Regular Expression in Python?A Regular Expression (RE) in a programming language is a special text string used for describing a search pattern. It is extremely useful for extracting information from text such as code, files, log, spreadsheets or even documents.
While using the Python regular expression the first thing is to recognize is that everything is essentially a character, and we are writing patterns to match a specific sequence of characters also referred as string. Ascii or latin letters are those that are on your keyboards and Unicode is used to match the foreign text. It includes digits and punctuation and all special characters like $#@!%, etc.
In this Python RegEx tutorial, we will learn-
For instance, a Python regular expression could tell a program to search for specific text from the string and then to print out the result accordingly. Expression can include
