title: Pyperclip copy causing an OSerror
body: <p>I am trying to learn python using <a href="https://automatetheboringstuff.com" rel="nofollow">https://automatetheboringstuff.com</a>. </p>
  
  <p>While on IDLE (Python 3.5 - 64 Bits), windows 8.1), pyperclip.copy('test') gives the following error message</p>
  
  <blockquote>
