How to call the count method on a context?

Question

Django

How to call the count method on the context to count the passed model objects when testing the pager? In its current form, the code is as follows, but I would like to avoid counting the length of the list:

response = self.client.get(reverse('index')) self.assertEqual(len(response.context['object_list']), 10)

When I did the tudushnik, I did this:
class TaskList(LoginRequiredMixin, ListView):
model = Task
context_object_name = 'tasks'
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context[' tasks'] = context['tasks'].filter(user=self.request.user)
context['count'] = context['tasks'].filter(complete=False).count()
context['k' ] = context['tasks'].filter(complete=True).count()
search_input = self.request.GET.get('search-area') or ''
if search_input:
context['tasks'] = context[ 'tasks'].filter(title__icontains=search_input)
context['search_input'] = search_input
return context
