Python RegEx or Regular Expression is the sequence of characters that forms the search pattern. RegEx can be used to check if the string contains the specified search pattern. The regular expression in a programming language is a unique text string used for describing a search pattern. It is beneficial for extracting information from text such as code, files, log, spreadsheets, or even documents. Now, let’s start a Python RegEx Tutorial with example.

Python regex

While using the regular expression, the first thing is to recognize that everything is essentially a character, and we are writing the patterns to match the specific sequence of characters also referred to as a string. The Ascii or Latin letters are those that are on your keyboards and Unicode is used to match a different text.

It includes the digits and punctuation and all the special characters like $#@!%, etc.

For instance, a regular expression could tell the program to search for a specific text from the string and then to print out the result accordingly. The phrase can include the following.

1. Text matching
2. Repetition
3. Branching
4. Pattern-composition etc.
