title: Need output in string type
body: <p>I have the input <code>s</code> of string. I want to print string <code>s</code> in which all the  occurrences of <strong>WUB</strong> are replaced with a white space.</p>
  
  <pre><code>s = input()
      print(s.split("WUB"))
  </code></pre>
  
  <p>Input : WUBWEWUBAREWUBWUBTHEWUBCHAMPIONSWUBMYWUBFRIENDWUB</p>
  
  <p>but the output I am getting is like this
   : <strong>['', 'WE', 'ARE', '', 'THE', 'CHAMPIONS', 'MY', 'FRIEND', '']</strong></p>
  
  <p>instead I need output in string format, like this  : <strong>WE ARE THE CHAMPIONS MY FRIEND</strong> </p>
