Triggering a button

Installing another add-on is probably a deal-breaker since that adds to the complication, so I dug a bit and found this thread:

How to detect an update/change of a number?

Hey together, I’m looking for a fast way to get a component which checks whether a number has been updated/changed. As long the number hasn’t changed the output should be „false“. Once the number changes the output should be ONE boolean of „true“ and should than switch back to „false“. I need it for a multi objective optimization where one of the plugin should be reset automatically after each iteration. Any ideas how to start with? Best, Kaspar

This handy little python script by @AndersDeleuran seems to do the trick just fine …
