title: Sort list of dictionaries with natsort to obtain natural sort order
body: <p>I'm looking for a method to sort a list of dicts to obtain a 'natural sort order'. I have found the module <code>natsort</code>, but apparantly I'm not using it right to get the list of dictionaries correctly sorted. Can anyone help to find my error?</p>
  
  <p>Here's my code:</p>
  
  <pre><code>from operator import itemgetter
  import natsort
  
  # Example list an dict
  list = ['13h', '1h', '3h']
  dict = [{'a': '13h', 'b': 3}, {'a': '1h', 'b': 1}, {'a': '3h', 'b': 0}]
  
  # Sort the list
  natsort.natsorted(list, key=lambda y: y.lower())
  
  # Sort the dict
  # Later I also want to sort on several keys, therefore the itemgetter
  sorted(dic, key=itemgetter(*['a']))
  </code></pre>
