title: "rank" each character in a string by the index at which they appear in the alphabet
body: <p>I don't know how to get for example from arr1 = ['johaj'] --&gt; arr2 = ['2','4','1','0','3']
  I'm not able to describe it very well what I mean so i hope you can understand it from this example. I need to get array of 'alphabetical indexes'.</p>
  <p>I would be very grateful for solution, how can I do this in Python.
  Thank you</p>
