Execute Workflow with Python - Inspect Output

I am interested in executing a workflow via python, as I am exploring if I could use this path to “autograde” assignments that students would submit.

The post below was helpful:

https://forum.knime.com/t/problem-to-launch-a-workflow-from-a-python-script/60885/15

My issue: My python script runs without error, but seemingly it doesnn’t return any data.

wf = knime.Workflow("/Users/path/knime-workspace/brock_test3")
wf.execute()
wf.data_table_outputs

Where

brock_test3

is the folder created after creating the flow in Knime. Here is the painfully simple flow that summarizes a publicly accessible csv.

I expected the output of the sorter node to made available as a data table after my code snippet ran.

I suspect that I am overlooking something obvious. Any help would be greatly appreciated.
