why is my code wrong?

If I get the array of Article objects, is just format the string output with the length of that array

articles/views.py 
from django.http import HttpResponse
from .models import Article
# Write your views here

def article_list(request):
  articles = Article.objects.all()
  output = "There are {0} articles".format(articles.len())
  return HttpResponse(output)

Sorry, I put articles.len() and the right way is len(articles), maybe I was confused with other programming languages that is the way to get the len of an array

Looks like you realized you needed len(array) on your own. :+1:

I'm not aware of a language that uses a method for length. I know in JavaScript it's a property (array.length).

C++ uses the length method for strings. 

my_str.length()

returns the number of characters in a string. Most of the other standard containers in C++ (arrays, lists, vectors, also strings as well) use the size method my_array.size() for the number of items inside them.
