Need an extra set of eyes to look this over.

I am trying to create a new view and the error I am getting back is kinda vague.

Can someone be my bug splatter?

articles/views.py 
#Now, create a view named article_list that selects all Article instances and returns an HttpResponse like "There are 5 articles." 
#Be sure to use the len() of the Article queryset to get the number of articles.

from django.http import HttpResponse

from .models import Article

def article_list(request):
    s = Article.objects.all()
    output = 'There are ' + len(s) + ' articles'
    return HttpResponse(output)

Django is probably complaining because you are trying to implicitly cast an int as a string.

You can use .format to fix your issue like so...

from django.http import HttpResponse

# Write your views here
from .models import Article

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

Correct, if updated with Ben Ackles comment below: "missing a period (.)"

Ryan, your solution does not work. Any ideas?

Ryan's solution works fine. The only problem is the string is missing a period (.) at the end. It's supposed to read "There are 5 articles."
