Suppose I create a a list values with 'values = [1,2,4,8]' in the pre-process script. How would I reference it in the post-process script? I initially assumed it would be results["values"] but

I believe you can store your variable in the workflow scope.

I think every piece of python code is sent separately to local process in the same SOAR console machine and processed as a snippet. In this case, you can't think on pre-process and post-process as part of the same processing unit. That's probably why SOAR has this concept of storing things in the workflow scope.

Please someone correct me if I am wrong. This is just the feeling I have about how things work behind the curtains.

Access to data in a script follows typical programming concepts. Any local variables defined in the script are only available to that instance of the script while it is running. If you want shared/global data you should store the data in the global data context.

In a workflow:

workflow.addProperty() / workflow.properties.<propertyname>

In a playbook:

playbook.addProperty() / playbook.properties.<propertyname>

These are available from the time they are first added to the time the workflow/playbook ends.

Here is an example in markdown https://github.com/ibmresilient/resilient-scripts/tree/master/python3/workflow#workflow of storing and accessing workflow properties. As ben says, replace workflow for playbook if you're running in that context.
