NameError: Name 'path' is not defined

[aniyanetworks]

Hello folks,
I am completely new in Python programming, and at beginning of the day, I am having some issues.
Hope you guys will help me pass through the issue.

The error shows on my CMD:
path(r'^admin/', admin.site.urls),
NameError: name 'path' is not defined

MySite:
urls.py-AboutUs

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

views.py

from django.http import httpresponse

def index(request):
return httpresponse ("<h1>Hello About us</>")

urls.py-My1stDjangoSite

from django.conf.urls import include, url
from django.contrib import admin
urlpatterns = [
path(r'^admin/', admin.site.urls),
path(r'^aboutus/', include('aboutus.urls')),
