Hi Emily

Here's the code that passed for me. I will walk you through it down below. I actually use f-string but not quite sure whether you know this so I'm going to put two solutions here which both work:

Using .format:

from django.http import HttpResponse

from .models import Article


def article_list(request):
    articles = len(Article.objects.all())
    output = 'There are {} articles.'.format(articles)
    return HttpResponse(output)

Using f-string:

from django.http import HttpResponse

from .models import Article


def article_list(request):
    articles = len(Article.objects.all())
    output = f'There are {articles} articles.'
    return HttpResponse(output)
  • first, we need to import all the necessary stuff
  • second, we create a view which you did correctly - def article_list(request):
  • on the next line we need to select all Article instances. We can do it like this: Article.objects.all(). We also need to assign it to a variable, in this case articles. In addition, we need to find the length of the Article queryset so the easiest way to do this is just to put it in the Python's length function len()
  • on the next line we assign the final answer to a output variable
  • lastly, we return the HttpResponse

I guess for the last two lines you can also do this:

return HttpResponse('There are {} articles.'.format(articles))

But I personally like to assign different stuff to variables. In this case the return line looks more readable.

I hope this helps!
