title: The output prints none and is not enclosed with ''
body: <pre><code>def isWordGuessed(secretWord, lettersGuessed):
      for char in secretWord:
  
          if char not in lettersGuessed:
              print('_',end=' ')
          else:
              print(char,end=' ')
  
  print(isWordGuessed('apple', ['e', 'i', 'k', 'p', 'r', 's']))
  </code></pre>
  
  <p>The output is <code>_pp_eNone</code></p>
  
  <p>I want my output to be <code>_pp_e</code> while still using the print function to call the function.</p>
  
  <p>What should I do?</p>
