title: Find all files with os.walk for a specific directory only
body: <p>A directory tree looks like this:</p>
  <pre><code>DirA--
       |
       -- Map
       |
       -- Fig--
              |
              --file.png
       |
       -- Data--
                |
                -- file.xls
                |
                -- file.csv
  </code></pre>
  <p>There are multiple directories, containing multiple files. I would like to get full path to those files that are found in <code>Data</code> directory only.</p>
  <p>This is what I have so far:</p>
  <pre><code>dirlist = []
  thisdir = os.getcwd()
  
  for root, dirs, files in os.walk(thisdir):
      for d in dirs:
          if d.startswith(&quot;Data&quot;):
              dirlist.append(os.path.join(root, d))
  </code></pre>
