title: Creating a dictionary with same values
body: <p>Suppose I have dictionary <code>a = {}</code> and I want to have it a result like this</p>
  
  <pre><code>value = 12
  a = {'a':value,'b':value,'f':value,'h':value,'p':value}
  </code></pre>
  
  <p>and so on for many <code>keys:same value</code>. Now of course I can do it like this</p>
  
  <pre><code>a.update({'a':value})
  a.update({'b':value})
  </code></pre>
  
  <p>and so on....
  but since the value is same for all the keys, don't we have a more pythonic approach to do this?</p>
