Prerequisite: Regex in Python
Given a string, write a Python program to check if the string is a valid email address or not.
An email is a string (a subset of ASCII characters) separated into two parts by @ symbol, a “personal_info” and a domain, that is personal_info@domain.
Input: firstname.lastname@example.org Output: Valid Email Input: email@example.com Output: Valid Email Input: ankitrai326.com Output: Invalid Email
In this program, we are using
search() method of re module. so let’s see the description about it.
re.search() : This method either returns None (if the pattern doesn’t match), or
re.MatchObject that contains information about the matching part of the string. This method stops after the first match, so this is best suited for testing a regular expression more than extracting data.
Let’s see the Python program to validate an Email :
