title: Launching Python script from Google Apps Script
body: <p>I've been searching for some time, and, as I couldn't find an answer, I'm asking this one. My issue is quite simple:</p>
  
  <p>I have a form linked to a sheet. Bound to this sheet, I have a script running, performing calculations based on the just inserted data, and taking actions. Although, I would like to perform a request on a given API. For so, I have a working script in python (something about 100 lines), and I'm not willing to rewrite it in JS (and I don't even know if that would be possible, considering some limitations on Google Apps Script JS), nor do I want to pay for Google App Engine. </p>
  
  <p>Is there anyway to run an external file, like a DOS command line, from my script in Google Apps Script?</p>
  
  <p>I've seen something similar <a href="https://stackoverflow.com/questions/22926456/trigger-python-code-from-google-spreadsheets">here</a>, but this doesn't fit my cases because the asker is willing to use GAE.</p>
  
  <p>Thanks in advance!</p>
