[SOLVED] django - About page not loading, all other views load.

This one is driving me crazy. I'm taking a Skillshare course on django. I'm trying to recreate perfectly what the instructor is doing on the screen. The two important files for this problem are urls.py and views.py.
Here's urls.py:
Code:"""tryjango URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/2.0/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path
from pages.views import home_view, contact_view, social_view, about_view
urlpatterns = [
path('', home_view, name='home'),
path('about/)', about_view),
path('social/', social_view),
path('contact/', contact_view),
path('admin/', admin.site.urls),
]And here's views.py:
Code:from django.http import HttpResponse
from django.shortcuts import render

# Create your views here.
def home_view(request, *args, **kwargs):
return render(request, 'home.html', {})
def contact_view(request, *args, **kwargs):
return HttpResponse("<h1>Contact Page</h1>")
def about_view(request, *args, **kwargs):
return HttpResponse('<h1>About page</h1>')
def social_view(request, *args, **kwargs):
return HttpResponse('<h1>Social Page</h1>')So far all my testing has worked. Except the about page. It gives me a 404, even though I spell it meticulously.
Code:Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/about/

Using the URLconf defined in tryjango.urls, Django tried these URL patterns, in this order:

[name='home']
about/)
social/
contact/
admin/

The current path, about/, didn't match any of these.

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.As you can see in my code above, the about page is coded the exact same as all the code around it. So why won't it map correctly?
