Python Django not running

Question

Firstly I installed Django using pip in my "CentOS" operating system. After that I performed these steps using terminal.

django-admin startproject mysite

a folder mysite is created with :

manage.py and another subfolder mysite

Then simply I just used these commands :

python manage.py runserver

and the server was running as clicked on the url : http://localhost:portnumber/

But after that when I made another app to run it is not running, my step are as follows :

python manage.py startapp webapp

Then one new folder created webapp in same mysite directory is created.

After changing settings.py and urls.py of mysite and also changing urls.py and views.py of webapp.

when I run :

python manage.py runserver

error is coming

    Performing system checks...

    appear to have any patterns in it. If you see valid patterns in the file   
    then the issue is probably caused by a circular import.

problem seems to be in the `urls.py` file of that app, care to show that. — lycuid, Oct 11 '16 at 05:47

This right here:

'/home/username/Desktop/prog/django/mysite/webapp/urls.pyc'>' does not appear to have any patterns in it.

Check urls.py

I can't tell you exactly what to check without seeing the file, but here is a sample urls.py:

urlpatterns = patterns('',
    # Examples:
    # url(r'^blog/', include('blog.urls')),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^webapp/', include('webapp.urls')),
)

codes are as follows : urls.py [/mysite/mysite/urls.py]

    from django.conf.urls import url,include
    from django.contrib import admin

    urlpatterns = [url(r'^admin/', admin.site.urls),
    url(r'^webapp/', include('webapp.urls'))
    ]

settings.py[/mysite/mysite/settings.py]

    INSTALLED_APPS = [
                       'webapp',
                       'django.contrib.admin',
                       'django.contrib.auth',
                       'django.contrib.contenttypes',
                       'django.contrib.sessions',
                       'django.contrib.messages',
                       'django.contrib.staticfiles',
                     ]

urls.py [/mysite/webapp/urls.py]

    from django.conf.urls import url
    from. import views

    urlpatterns = [
                    url(r'^$', views.index, name='index')
                   ]

views.py [/mysite/webapp/views.py]

    from django.shortcuts import render
    from django.http import HttpResponse

    def index(request):
          return HttpResponse("<h2>Hey!</h2>")

So did changing urls.py fix the issue? I can't tell from your edit. — brt, Oct 13 '16 at 04:29
