title: Range with alphabets Python
body: <p>Suppose I have a list like this <code>string = ['A1', 'A5']</code>, I want to create a new list which should start from <code>A1</code> and end at <code>A5</code>.</p>
  
  <p><strong>E.g</strong> <code>['A1','A5'] -&gt; ['A1','A2','A3','A4','A5']</code></p>
  
  <p>Similarly for this case <code>['A1', 'C1'] -&gt; ['A1','B1','C1']</code>.</p>
  
  <p>My approach was to create a LinkedList node for A1 and then increment the integer constant with every new creation of node and then append them together.</p>
  
  <p>How can this be done?</p>
