title: Python webbrowser open doesn't open url that has been stored in variable
body: <p>I just have a simple question. When I do something like</p>
  
  <pre><code> import webbrowser
  
   webbrowser.open('www.google.com')
  </code></pre>
  
  <p>it works,and opens a page using my default browser
  However,when I store the url in a variable, it doesn't open it..doesn't throw up any errors or anything either.. something like:</p>
  
  <pre><code> import webbrowser
  
   url=raw_input("Enter url")
   webbrowser.open(url)
  </code></pre>
  
  <p>Anyone have any ideas as to why this might be happening?</p>
