body: <p>I have an if statement: </p>
  
  <pre><code>rules = input ("Would you like to read the instructions? ")
  rulesa = "Yes"
  if rules == rulesa:
      print  ("No cheating")
  else: print ("Have fun!")
  </code></pre>
  
  <p>I wish for the user to be able to answer with Yes, YES, yES, yes or any other capitalisation, and for the code to know that they mean Yes. </p>
