title: Exit 0 vs. Return 0 Python Preference
body: <p>I'm using a Python script to farm out some subprocesses to some other Python scripts. I need to make sure the Python subprocesses run successfully. Is there a convention on whether it is better to <code>exit(0)</code> or <code>return 0</code> at the end of a successfully run Python script?</p>
  
  <p>I don't think it matters from a functional perspective, but I'm wondering whether one is preferred.</p>
