Simple email validation in python

Email validation is lot more complicated than it seems.  A real validation will take this pretty looking regex to implement. 

So here is a very very basic email validation to your rescue,

import re
def is_email(email):
    pattern = '[\.\w]{1,}[@]\w+[.]\w+'
    if re.match(pattern, email):
        return True
    else:
        return False

All it does is checking:

• must have ‘@’ and ‘.’
• at least one character before ‘@’ [yes I know about the '_', as I said, its very basic]
• at least one character after ‘@’
• at least one character after ‘.’
