title: while loop with strings only runs once
body: <p>I am having a hard time trying to figure out what is wrong with this code. Can someone tell me what is wrong with this while loop? It will only run once.</p>
  
  <pre><code>i= input("Please enter I to report or enter Exit to exit. ")
  while i.lower == "i":
      print("in loop")
  
      #to rerun code or exit it
      i = input("Please enter I to report  or enter Finish to exit. ")
  
  print("done")
  </code></pre>
