Question

Hi i was looking for a way to verify the domain with a provided email address
The domain names can be
http://www.test.free.com
http://www.free.com.au
http://www.free.com.au.org
http://www.free.com.org
or there can be a domain name with any number of sub sub domains and any number of verifications.

the verifying email should contain the domain and this is what i wrote so far

if domain_url is not None and verification_email is not None:

    logging.info('==============================')
    logging.info('BOTH WERE NOT NONE')
    logging.info('==============================')

    domain_email = verification_email.split('@')[1].split('.')[0]

    logging.info('==============================')
    logging.info(domain_email)
    logging.info('==============================')

    verify_domain_url_list = domain_url.split('.')

    if len(verify_domain_url_list) == 4:
        verify_domain_url_list.pop()
        verify_domain_url_list.pop()
    if len(verify_domain_url_list) == 3:
        verify_domain_url_list.pop()


    verify_status = domain_email in verify_domain_url_list

    if verify_status:
        return 'yes'
    else:
        pre_domain_address = verify_domain_url_list[0].split('//')[1]
        if pre_domain_address is not None and \
            domain_email in pre_domain_address:
            return 'yes'
        else:
            return 'no'
    return 'no' 

but this not matching for all the possibilities. can any one give a help?

Answer 1

You can do it like this, just add the new domains inside the parenthesis.

verification_email = '[e-mail]'
pattern = r'.*@(test.free.com|free.com.au|free.com.au.org|free.com.org)$'

import re
if re.search( pattern , verification_email):
    print('yes')
    # or on your case, return 'yes'
