title: Python - get the last element of each list in a list of lists
body: <p>My question is quite simple, I have a list of lists :</p>
  
  <pre><code>my_list = [['a1','b1'],['a2','b2'],['a3','b3','c3'],['a4','b4','c4','d4','e4']]
  </code></pre>
  
  <p>How can I get easily the the last element of each list i.e. :</p>
  
  <pre><code>[ 'b1' , 'b2' , 'c3' , 'e4' ]
  </code></pre>
  
  <p>Thanks !</p>
