title: Move child folder contents to parent folder in python
body: <p>I have a specific problem in python. Below is my folder structure.</p>
  <p><code>dstfolder/slave1/slave</code></p>
  <p>I want the contents of <code>'slave'</code> folder to be moved to <code>'slave1'</code> (parent folder). Once moved,
  <code>'slave'</code> folder should be deleted. <code>shutil.move</code> seems to be not helping.</p>
  <p>Please let me know how to do it ?</p>
