title: Define a dictionary with a name already stored as a string in the script
body: <p>I would like to define a dictionary with a name that changes dynamically.
  For example:</p>
  
  <pre><code>Dictname = 'Forrest'
  Forrest = {}
  </code></pre>
  
  <p>The parameter Dictname is received from a textfile, the value forrest will be different every time the script runs</p>
