7,493 Pointswhy is my code wrong?
If I get the array of Article objects, is just format the string output with the length of that array
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)

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

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.

7,493 PointsSorry, 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
