Part 3 – Calling playbooks (Markdown ↔ Python)

Audience: Intermediate

Goal: Compose Markdown and Python playbooks on one call stack.

Run the examples

Markdown calls Python and back:

playbooks run tests/data/03-md-calls-python.pb

Python interop:

playbooks run tests/data/playbooks-python-interop.pb

Round‑trip:

playbooks run tests/data/04-md-python-md.pb

Concepts:

• @playbook Python functions
• Arguments and return values
• Mixed execution on a unified call stack

See also:

• Python Playbooks
• Markdown Playbooks
• Triggers
