title: Execute npm Script in a different Folder with python
body: <p>Can someone tell me how I can do &quot;npm run start&quot; in any folder using a Python script. But please with the &quot;os&quot; operator and not &quot;subprocess&quot;.</p>
  <p><strong>EDIT:</strong>
  I need a python script, that goes to a specific folder and then executes
  &quot;npm run start&quot;. How can I do that?</p>
