title: Python - Get relative path of all files and subfolders in a directory
body: <p>I am searching for a good way to get relative paths of files and (sub)folders within a specific folder. </p>
  
  <p>For my current approach I am using <code>os.walk()</code>. It is working but it does not seem "pythonic" to me:</p>
  
  <pre><code>myFolder = "myfolder"
  fileSet = set() # yes, I need a set()
  
  for root, dirs, files in os.walk(myFolder):
      for fileName in files:
          fileSet.add(root.replace(myFolder, "") + os.sep + fileName)
  </code></pre>
  
  <p>Any other suggestions?</p>
  
  <p>Thanks</p>
