What is the problem in this code? Please arti = Article.objects.all() return HttpResponse("There are "+ arti.len())

arti = Article.objects.all() return HttpResponse("There are "+ arti.len())

i did too

return HttpResponse("There are {0}". format(arti.len()))

articles/views.py 
from django.http import HttpResponse
from .models import Article
# Write your viewdef article_list s here
def article_list(request):
    arti =  Article.objects.all()
    return HttpResponse("There are articles " + arti.len())

len is a built-in function, not a method that can be run on Django object sets or whatever they call them. You instead have to pass the item you want the length of, into the len() function:

    return HttpResponse("There are articles " + len(arti))

or if you want to use format also:

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