Can I know why is my question considered wrong and how can I print the length of the instances retrieved from the database in the correct way?
from django.http import HttpResponse
from .models import Article
def article_list(request):
article= Article.objects.all()
article=str(article)
return HttpResponse("There are ",article.len(), "articles ")

Treehouse TeacherHi there! There are a couple of things going on here that are causing problems. First, you are not using the len() method correctly. To get the length of an iterable item you should be using len(item). Also, commas inside the parentheses for a method denote arguments and are not concatenation operators. It is not necessary to turn the number into a string. My advice is to try string interpolation. Even if your string worked in this fashion, it is still missing a space before "articles" and a full stop/period. This will result in the incorrect string format required by the challenge For example:
word = "Hello"
result = len(word)
print("The length of the word is {}.".format(result))
This would print out: The length of the word is 5.
Hope this helps, but let me know if you're still stuck!
