Django: assertEquals with visually equal result with QuerySet

Can anybody explain me why these have the same values, but don't compare equal? Having a bit of a hard time to understand that. And what would be the best way to make them be "equal"?

Inspection using ipdb:

ipdb> expected_value                                                                                                                                  
{'author': 'john', 'id': 1, 'title': 'Yesterday', 'body': 'All my troubles seemed so far away', 'tags': <QuerySet ['Music', 'Lyrics']>}
ipdb> response                                                                                                                                        
{'author': 'john', 'id': 1, 'title': 'Yesterday', 'body': 'All my troubles seemed so far away', 'tags': <QuerySet ['Music', 'Lyrics']>}

Pieces of code:

class TestPost(TestCase):                                                                                               

    def test_serialize(self):                                                                                           
        user = User.objects.create(username="john", password="12345678", email="john@exemplo.com")                      
        tag1 = Tag.objects.create(value="Music")                                                                        
        tag2 = Tag.objects.create(value="Lyrics")                                                                       
        post = Post.objects.create(author=user, title="Yesterday", body="All my troubles seemed so far away")           
        post.tags.add(tag1)                                                                                             
        post.tags.add(tag2)                                                                                             

        expected_value = {                                                                                              
            "author": user.username,                                                                                    
            "id": user.id,                                                                                              
            "title": post.title,                                                                                        
            "body": post.body,                                                                                          
            "tags": post.tags.all().values_list("value", flat=True),                                                    
        }                                                                                                               
        response = post.serialize()                                                                                                                                      
        self.assertEqual(expected_value, response)

and the Django model that I was testing

class Post(models.Model):                                                                                               
    author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, blank=False, null=False,)            
    title = models.CharField(blank=False, null=False, validators=[MinLengthValidator(3)], max_length=50)                
    body = models.CharField(blank=False, null=False, validators=[MinLengthValidator(5)], max_length=1000)               
    tags = models.ManyToManyField("Tag")                                                                                

    def serialize(self):                                                                                                
        return {                                                                                                        
            "author": self.author.username,                                                                             
            "id": self.id,                                                                                              
            "title": self.title,                                                                                        
            "body": self.body,                                                                                          
            "tags": self.tags.all().values_list("value", flat=True),                                                    
        }
