Set command in the queue for delayed evaluation?

I am running some commands that take several hours to finish. I would generally run it overnight. After it's finished, I would like to be able to automatically run a different file which may depend on the output of first one.

Is it possible to do this programmatically? As in, to tell Pycharm what to execute after the current evaluation has finished?

I am using Pycharm with Python.

Thank you
