title: Remove a set string from many directories in Python
body: <p>I have a folder <code>/users/my/folder</code> which contains many folders which all have names that end with <code>_STAGE copy</code>. I would like to remove the end of the folder name <code>_STAGE copy</code> and keep everything before it in the folder name. </p>
  
  <p>I have found examples to provide the before/after name, but none that will remove a particular string in bulk from many folders within a directory. </p>
  
  <p>This seems painfully simple but I'm having a hard time figuring it out</p>
