title: Python: How to apply sorting (by max value) of one list to element index sorting of another list
body: <p>e.g.</p>
  
  <pre><code>lst1=['1.11','3.34','2.44','4.5']
  lst2=['100.0','5000.9','999.0','666.0']
  </code></pre>
  
  <p>I want to sort the values in lst1 from max to min which I can do as follows:</p>
  
  <pre><code>lst1_sorted=sorted(lst1,key=float,reverse=True)
  
  lst1_resorted = ['4', '3', '2', '1']
  </code></pre>
  
  <p>but then I also want to use the sorting on lst2 so that </p>
  
  <pre><code>lst2_resorted = ['666','5000','999','100']
  </code></pre>
  
  <p>This needs to work specifically for list entries which are floating point numbers. E.g. I can use key=float above. Ideally without having to import another library.</p>
