body: <p>I have a dictionary:</p>
  <pre><code>dict1={'scope1': 'manager', 'scope2': 'om'}

  <p>I want that if I have another <code>&quot;scope2&quot;</code>  and values as <code>&quot;fm&quot;</code> in the for loops evaluation, then the &quot;scope2&quot; keys value should now become = <code>['om', 'fm']</code>.</p>
