Solve the following python programming problem given the following code:
@ pytest.mark.registerable () 
def test_confirmable_flag(app, client, sqlalchemy_datastore, get_message) : 
    recorded_confirms = [] 
    recorded_instructions_sent = [] 
    @ user_confirmed.connect_via (app) 
    def on_confirmed(app, user) : 
        assert isinstance (app, Flask) 
        assert isinstance (user, UserMixin) 
        recorded_confirms.append (user) 
@ confirm_instructions_sent.connect_via (app) 
    def on_instructions_sent(app, user) : 
        assert isinstance (app, Flask) 
        assert isinstance (user, UserMixin) 
        recorded_instructions_sent.append (user) 
email = 'dude@lp.com' 
    with capture_registrations () as registrations : 
        data = dict (email = email, password = 'password', next = '') 
        response = client.post ('/register', data = data) 
assert (response.status_code == 302) 
    response = authenticate (client, email = email) 
    assert (get_message ('CONFIRMATION_REQUIRED') in response.data) 
    response = client.get ('/confirm/bogus', follow_redirects = True) 
    assert (get_message ('INVALID_CONFIRMATION_TOKEN') in response.data) 
    response = client.post ('/confirm', data = '{"email": "matt@lp.com"}', headers = { 
        'Content-Type' : 'application/json', 
}) 
    assert (response.status_code == 200) 
    assert (response.headers ['Content-Type'] == 'application/json') 
    assert ('user' in response.jdata ['response']) 
    assert (len (recorded_instructions_sent) == 1) 
    response = client.post ('/confirm', data = dict (email = 'bogus@bogus.com')) 
    assert (get_message ('USER_DOES_NOT_EXIST') in response.data) 
    response = client.post ('/confirm', data = dict (email = email)) 
    assert (get_message ('CONFIRMATION_REQUEST', email = email) in response.data) 
    assert (len (recorded_instructions_sent) == 2) 
    token = user [0] ['confirm_token'] 
    response = client.get (('/confirm/' + token), follow_redirects = True) 
    assert (get_message ('EMAIL_CONFIRMED') in response.data) 
    assert (len (recorded_confirms) == 1) 
  ...

    
    

    Fix the buggy line: token = user [0] ['confirm_token']

#Here is Python program to fix the buggy line: token = user [0] ['confirm_token']
.

token = registrations [0] ['confirm_token']
