"""A Python workflow that prompts the user.

    python interactive_workflow.py

A ``FunctionTask`` can ask the user questions through ``task.interaction``. When
running under the live TUI, the dashboard pauses while the prompt is shown and
resumes once you answer. YAML workflows cannot do this; it needs real Python.
