  <pre><code>dict1= {'CNN': '0.000002'}
  
  s=dict1.values()
  print (s)
  print (type(s))
  </code></pre>
  
  <p>What I am getting is:</p>
  
  <pre><code>dict_values(['0.000002'])
  &lt;class 'dict_values'&gt; # type, but need it to be float
  </code></pre>
  
  <p>but what I want is the float value as below:</p>
  
  <pre><code> 0.000002
   &lt;class 'float'&gt; # needed type
  </code></pre>
