Django: django.urls 'den ithal; ImportError: URL'ler

Question

adlı bir modül yok Polska uygulaması ile DjangoProject öğreticisi üzerinden çalışıyorum. Ben almak için çalışıyorum parçası 4'te öğretici devletler gibi 'ters': from django.urls import reverse ama hata alıyorum:

from django.urls import reverse ImportError: No module named urls

Sadece 'urls' Ancak o da işe yaramadı için ROOT_URLCONF değişti.

Herhangi bir yardım için teşekkür ederiz, Teşekkürler.
