Just wondering why my code here isn't passing? I've spent two hours going back over the video, looking in the Django documentation, etc. Not sure what I'm missing.
from django.http import HttpResponse
from .models import Article
# Write your views here
def article_list(request):
articles = Article.objects.all()
output = len(articles)
return HttpResponse("There are" + output + " articles")

15,358 PointsSolved by using:
from django.http import HttpResponse
from .models import Article
# Write your views here
def article_list(request):
articles = Article.objects.all()
output = ' '.join(['There are',str(len(articles)),'articles.'])
return HttpResponse(output)

Courses Plus Student 1,190 PointsCan't you do that kind of string concatenation (as you would do in say JavaScript) in Python? What's the deal with that?
The way you tried to do it, is the way I tried to to do it, and it looks much nicer to me :P

Courses Plus Student 1,190 PointsAh!
I figured out what you originally had incorrect.
The output variable was holding a number, you need to do str(output), so that it is a string. You can't concatenate a number to a string :)

11,271 PointsThanks! Forgot that you can't concatenate strings and numbers. But join() is not necessary. Here's a simpler and more readable way:
def article_list(request):
num_articles = len(Article.objects.all())
return HttpResponse("There are " + str(num_articles) + " articles.")
