Hey, you're nearly there, but in this case you don't need an extra output variable, Kenneth only does that in the video because he wants to return a list of the items not the amount that they have.

  • You'd just need to use len() on articles like this: len(articles)
  • When you concatenated the string you also forgot the commas separating the string and variable I decided to use a f-string but you don't need to.

This is my example if you need any more help.

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

Thank you! Just a quick question, what is the 'f' after HttpResponse?

Oh that’s an f string it’s just another way to format it, you can use .format() aswell but I prefer f-strings I find them to be cleaner and easier to read when you have more than 4 variables.

This is how you’d use .format()

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