How to validate an e-mail address - Python

Dec 11, 20 / 2 comments / #Python

Every now and then, we want to check if an e-mail address is valid. Maybe you're building a user sign up or a newsletter registration form?

# Import regex library
import re

# Regex
regex = '^[a-z0-9]+[\._]?[a-z0-9]+[@]\w+[.]\w{2,3}$'

# Create a simple function
def check(email):  
  if(re.search(regex,email)):  
    return True
  else:
    return False

# Checks

>>> check('codewithstein@gmail.com')
True

>>> check('codewithsteingmail.com')
False
