title: Move object in pandas DataFrame from one "cell" to another
body: <p>I need to move an object in a pandas DataFrame from one location to another, and leave the original location of that object blank without affecting other columns.</p>
  
  <pre><code>employees = [0, 0, 0, 1, 0, 0, 0, 0, 0, 0]
  levels = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
  
  df = pd.DataFrame({"Employees":employees, "Level":levels})
  
  #move employee 1 from index 3 to index 1 without altering Level column
  #leave index 3 blank after moving employee 1
  </code></pre>
  
  <p>Visually, I need to go from <a href="https://i.stack.imgur.com/jcSSa.png" rel="nofollow noreferrer">starting point</a> to <a href="https://i.stack.imgur.com/iIvOJ.png" rel="nofollow noreferrer">end point</a>.</p>
  
  <p>Thank you!</p>
