title: Creating a pull down menu with folders in NUKE python
body: <p>I am trying to create a pull down in NUKE to list all the folders in a path. Here is my code so far:</p>
  
  <pre><code>p = nuke.Panel('my custom panel')
  p.addEnumerationPulldown('my choices', (os.walk('E:').next()[1]))
  ret = p.show()
  </code></pre>
  
  <p>A problem I have is if I have a folder name with spaces in it, it shows up as different choices..<br>
  For example the folder <code>System Test</code> shows up as two choices <code>System</code> and <code>Test</code></p>
  
  <p>How can I fix this?</p>
