title: How do I append a string to a Path in Python?
body: <p>The following code:</p>
  
  <pre><code>from pathlib import Path
  Desktop = Path('Desktop')
  SubDeskTop = Desktop + "/subdir"
  </code></pre>
  
  <p>gets the following error: </p>
  
  <pre><code>    ---------------------------------------------------------------------------
   TypeError                                 Traceback (most recent call last)
      &lt;ipython-input-4-eb31bbeb869b&gt; in &lt;module&gt;()
               1 from pathlib import Path
               2 Desktop = Path('Desktop')
         ----&gt; 3 SubDeskTop = Desktop+"/subdir"
  
       TypeError: unsupported operand type(s) for +: 'PosixPath' and 'str'
  </code></pre>
  
  <p>I'm clearly doing something shady here, but it raises the question:  How do I access a subdirectory of a <code>Path</code> object?</p>
