title: python dictionary- two keys to each value
body: <p>Hi I am fairly sure you can't do this but I was wondering if you could have a dictionary where each of the values can be accessed via two keys without duplicating the dictionary.</p>
  
  <p>The reason I want to do this is that the two keys will represent the same thing but one will be a shortened version eg. 'TYR' and 'Y' will both have the same value. </p>
