title: URL Regular Expression mismatch
body: <p>I am trying to learn Django and I am currently stuck in an issue.</p>
  
  <p>I created an app Contact and run the server, I get the error.</p>
  
  <p>The error page displayed by server:</p>
  
  <p><a href="https://i.stack.imgur.com/Z9H90.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Z9H90.png" alt="enter image description here"></a></p>
  
  <p>The urls.py file in the app Contact</p>
  
  <p>urls.py in conatct</p>
  
  <p><a href="https://i.stack.imgur.com/fVALb.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/fVALb.png" alt="enter image description here"></a></p>
  
  <p>When the pattern in urls.py is 
  urlpatterns =[url(r'^$', views.form, name ='form')]
  it works properly, but not with other pattern shown in the picture</p>
  
  <p>Your help would be greatly appreciated.</p>
