title: equivalent of raw_input in Ipython notebook
body: <p>I am just messing around with Ipython notebook, and I was going to create a battleship game...unfortunately I need lines like the following in the code in order to make a game like that:</p>
  
  <pre><code>move = raw_input("Where would you like to attack? ")
  </code></pre>
  
  <p>Ipython notebook does not allow raw_input...so how could I get input from one of the players? I have searched around and nothing I could find had a direct answer to this such as no you can't or yes and this is how. Thanks.</p>
