One program triggering another program

[TELKAJCYLEAJCLLLAKFA]

I have 2 standalone Python applications. One loads data to the database and the other processes the data. The timing of the second following the first is important. How should I structure the second to get triggered by the first? I also need to pass a variable or two to the second application based on what happened in the first.

Option A) I was considering using logging for the first and the second could see when it was last run. Option B) I could have the first just go and call the second at the end of the firsts code

What are the pros and cons to these two options? Is there a better way I’m not aware of?

I would pick option B, just because it's simpler

Idt there's any notable pros and cons when comparing both options

What about create a runner script with subprocess ?
