No module named django.urls - django-models

Question

I'm trying to create a new model, i named it products, and i found this error message which you see below
Note that my django version is 1.8.7
##urls.py:
from django.contrib import admin
from mySecondGdgBlogs import views
from django.urls import include, path
from myGdgBlogs import views
urlpatterns = [
path('admin/', admin.site.urls),
path('writeafterme/',include('mySecondGdgBlogs.urlss')),
path('htm/', views.htamal),
path('dp/',views.dpmain)
]
##views.py:
from django.http import HttpResponse
from django.shortcuts import render
# Create your views here.
def dbmain(request):
data = ''
return HttpResponse(data)
##models.py
from django.db import models
# Create your models here.
class Products(models.Model):
name = models.CharField (max_length=20)
price = models.IntegerField()
type=models.CharField(max_length=20,choices=(
('S', 'Small'),
('M', 'Medium'),
('L', 'Large'),
))
class Meta:
db_table = 'Products'
I expected to show me a white page but the actual result in the browser is :
