title: How to execute Python function when value in SQL table changes?
body: <p>I am having trouble finding this answer anywhere on the internet. I want to be able to monitor a row in a MySQL table for changes and when this occurs, run a Python function. This Python function I want to run has nothing to do with MySQL; it just enables a pin on a Raspberry Pi. I have tried looking into SQLAlchemy; however, I can't tell if it is a trigger or a data mapping. Is something like this even possible?</p>
  
  <p>Thanks in advance!</p>
