title: Running python script as another user
body: <p>On a Linux box I want to run a Python script as another user.</p>
  
  <p>I've already made a wrapper program in C++ that calls the script, since I've realized that the ownership of running the script is decided by the ownership of the python interpreter. After that I change the C++ program to a different user and run the C++ program.</p>
  
  <p>This setup doesn't seem to be working. Any ideas?</p>
