Problema ao alterar a mensagem inicial | Django: programação web com Python e simplicidade

Olá, minha aplicação está dando o seguinte erro:

urls.py

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

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^$','perfis.views.index')
]

views.py

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

def index(request):
    return HttpResponse('Bem-vindo ao Connectedin')

Aqui o código que vc usou no connectedin.urls.py deu certo. Desconfio que seja problema de versão. Sua versão do Django é a requerida para o curso (1.7.x)?

Se não for, experimente corrigir o código de connectedin.urls.py para este:

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

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

A diferença deste código para o seu é que, ao invés de informar uma rota usando o caminho para view numa string, estamos passando (incluindo) a lista de urls do app perfis. Esse tipo de configuração, se não me engano, é a requerida nas versões mais novas do Django ( a partir da 1.10).
