How do I return .len() in the HttpResponse()?

I just have no idea how to return the length in the HttpResponse method. This may have more to do with my unfamiliarity with Python than anything else...

articles/views.py 
from django.http import HttpResponse
from .models import Article

def article_list(request):
    length = Article.objects.all().len()
    return HttpResponse('(%d)' % length)

There's just a few things that I'm noting. len is not a method of the QuerySet returned by Article.objects.all(). You could use the method called count, but they are asking you to use len which is a built in function. The other thing is that you aren't returning the string that the challenge wants you to return. That is an easy fix.

from django.http import HttpResponse
from .models import Article

def article_list(request):
    length = len(Article.objects.all())  # Call len as a function and not as a method
    return HttpResponse('There are %d articles.' % length)  # Return the proper string

Those two things should complete the challenge for you.
