Check if email address valid or not in Python
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.

Examples:
Input: ankitrai326@gmail.com Output: Valid Email Input: my.ownsite@ourearth.org Output: Valid Email Input: ankitrai326.com Output: Invalid Email
In this program, we are using the search() method of re module. so let’s see the description of it.
re.search() : This method either returns None (if the pattern doesn’t match), or re.MatchObject 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 :
Python3
# Python program to validate an Email# import re module# re module provides support# for regular expressionsimport re# Make a regular expression# for validating an Emailregex = r'\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b'# Define a function for# for validating an Emaildef check(email): # pass the regular expression # and the string into the fullmatch() method if(re.fullmatch(regex, email)): print("Valid Email") else: print("Invalid Email")# Driver Codeif __name__ == '__main__': # Enter the email email = "ankitrai326@gmail.com" # calling run function check(email) email = "my.ownsite@our-earth.org" check(email) email = "ankitrai326.com" check(email) |
Valid Email Valid Email Invalid Email
