Python Django Basics Test Time Test our Writer model

I'm not sure how self.assertIn and mailto() work

I couldn't figure out how to complete the WriterModel test. I tried doing something similar to the test you covered in the video. I assume self.assertIn sees if object a is in list b. What am I missing?

articles/tests.py 
from django.test import TestCase
from .models import Writer


class WriterModelTestCase(TestCase):
    '''Tests for the Writer model'''
    def test_writer_creation(self):
        writer = Writer.objects.create(
         name="Sally",
         email="sally@jupiter.com",
         bio="My name is Sally"
        )

    self.assertIn(email, mailto(writer))
articles/models.py 
from django.db import models


class Article(models.Model):
    headline = models.CharField(max_length=255)
    publish_date = models.DateTimeField()
    content = models.TextField()
    writer = models.ForeignKey('Writer')

    def __str__(self):
        return self.headline


class Writer(models.Model):
    name = models.CharField(max_length=255)
    email = models.EmailField()
    bio = models.TextField()

    def __str__(self):
        return self.name

    def mailto(self):
        return '{} <{}>'.format(self.name, self.email)
