title: Mathematical operation on a dictionary list (python 3.6)
body: <p>I am using python 3.6 and i have a list of dictionaries like this:  </p>
  
  <pre><code>list = [{'name': 'A', 'number':'1'}, {'name': 'B', 'number':'2'}, {'name': 'C', 'number':'3'}, {'name': 'D', 'number':'4'}]
  </code></pre>
  
  <p>I found out how to print the list in the desired format with:</p>
  
  <pre><code>for s in list:
       name = s['name']
       number = s['number']
       print(name + " = "+ number)
  </code></pre>
  
  <p>Wich give:</p>
  
  <blockquote>
    <p>A = 1<br>
    B = 2<br>
    C = 3<br>
    D = 4</p>
  </blockquote>
  
  <p>I would like to be able to multiply the items 'number' by 2 for example and display:</p>
  
  <blockquote>
    <p>A = 2<br>
    B = 4<br>
    C = 6<br>
    D = 8</p>
  </blockquote>
  
  <p>Thank you!</p>
