I am a beginner in Django and facing a syntax error in urls.py

Here is my personal/urls.py. I have been trying to solve this for quite a few days. I know it must be a really silly error but help would be appreciated.

from django.conf.urls import url, include
from . import views
urlpatterns = [
url(r'^$',views.index, name='index'),
url(r'contact/',views.contact, name='contact')
url(r'about/',views.about, name='about')
]

And here is the views.py

def index(request):
return render(request, 'personal/home.html')

def contact(request):
return render(request, 'personal/basic.html', {'content': 
['http://ift.tt/2upkuqI']})

def about(request):
return render(request, 'personal/about.html', {'content': ["This is an abut 
page"]})
