title: Pre-initialize raw_input with default value
body: <p>I have a "form" where I have a few <code>raw_input</code>s to get the user response.</p>
  
  <p>Now I want them to be pre-initialized with a default value. Is there any way to fill these <code>raw_input</code> fields? Or is there a good alternative to <code>raw_input</code> where that is possible?</p>
  
  <p>To clarify, I have something looking like this:</p>
  
  <pre><code>val = raw_input("Input val:")
  </code></pre>
  
  <p>What I want as output is the following:</p>
  
  <pre><code>Input val: default value
  </code></pre>
  
  <p>and I want the user to be able to erase or edit the default value as if they had written it themselves. Is there any way to do that?</p>
