title: Checking whitespace in a string (python)
body: <p>Why do I always get <code>YES!!!</code>? I need to return <code>NO!!!</code> if the string contain a whitespace (newline, tap, space)</p>
  
  <pre><code>user = "B B"
  
  if user.isspace():
      print("NO!!!")
  else:
      print("YES!!!")
  </code></pre>
