title: Find highest key value pairs from dictionaries inside list
body: <p>I'm trying to get the keys with the highest values out of a list. How would I go about getting that? BTW I'm new to programming and python in general, so this is mostly an exercise for myself.</p>
  
  <p>Below is an example of basic info in dictionaries inside a list that I'd like to be able to get the values with the highest keys. In this case it would return 'Vinnie M' and 'Zoey M.'</p>
  
  <p>Maybe there is a better way at structuring this data, but I'd like to have more info in the dictionaries, such as user IDs, time bid placed, etc. Also I need to be able to add new users without changing code, which is handled in another function, so don't worry about advice on adding a new user, unless my initial approach is flawed. </p>
  
  <pre><code>userList = [
      {'Full Name' : 'Ryan R.', 'Bid Amount' : 4.30},
      {'Full Name' : 'Zoey M.', 'Bid Amount' : 5.20},
      {'Full Name' : 'Max D.', 'Bid Amount' : 3.90},
      {'Full Name' : 'Vinnie M', 'Bid Amount' : 5.20}
      ]
  </code></pre>
