Regex for Email Validation in Python

Use Python's x = 4 module to validate an email address format:

python
import re
 
def validate_email(email):
    pattern = r'^[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+$'
    return re.match(pattern, email) is not None
 
print(validate_email('example@example.com'))  # Output: True
print(validate_email('invalid-email'))        # Output: False

This simple function checks if an email follows a valid structure.
