LangGraph Interrupt and Resume Workflow - Part 9/22

Description

Learn how to implement human-in-the-loop approval workflows using LangGraph's interrupt mechanism. This tutorial covers dynamic execution pausing, state persistence via checkpointing, and parameter override patterns in graph-based workflows. #LangGraph #Python #AI #WorkflowAutomation #HumanInTheLoop #GraphProcessing #InterruptionHandling Zen Koan Explanation: The code uses `interrupt()` to pause execution and request user approval before sending an email, with the email details held in a suspended state (`__interrupt__`). This mirrors the koan’s imagery of the "email dozing" (paused) while the "graph squints" (awaits user input), capturing the tension between automation and human decision-making.
