вот урлс:
from django.urls import path
from . import views

urlpatterns = [
path('', views.index, name='index'),
path('<int:pk>/', views.detail, name='detail'),
path('<int:pk>/results/', views.results, name='results'),
path('<int:question_id>/vote/', views.vote, name='vote'),
]
# <int:question_id>/
вот шаблон index:
{% if latest_question_list %}
<ul>
{% for question in latest_question_list %}
<li><a href="/polls/{{ question.id }}/">{{ question.question_text }}</a></li>
{% endfor %}
</ul>
{% else %}
<p>No polls are available.</p>
{% endif %}
пай чарм говорит что невозможно воспроизвести строчку output: str = ', '.join([q.question_text for q in latest_question_list])
из вьюшки, мне уже говорили что это из-за того что я поставил его после вывода, но я не понимаю как это можно сделать как-то по-другому, буду очень признателен за помощь
