title: Python error: TypeError: '_csv.reader' object is not subscriptable
body: <p>I am working on creating a change calculator that has to output a result similar to this: </p>
  
  <pre><code>{'TWENTY':1, 'TEN':1, 'FIVE':1, 'PENNY’ : 2}
  {‘ONE’:1,'FIVE':1}
  {‘ONE’:1}
  {'PENNY':4,'NICKEL':1}
  </code></pre>
  
  <p>I am having issues with reading the data and accessing the indices because I have never worked with reading a .csv file before. I think the logic of my calculator should be fine. I realize there are more efficent ways to code it but I am on a time limit and this seemed logical to me. Any help is appreciated.</p>
  
  <p>Thanks</p>
