LangGraph Interrupt and Resume Workflow - Part 11/22

Description

Learn how to implement dynamic workflow interruptions in LangGraph using the interrupt() function for human-in-the-loop validation. This tutorial covers persistent state management with checkpoints, iterative input validation loops, and JSON-serializable payload handling in Python-based graph execution. #LangGraph #Python #WorkflowAutomation #AI #InteractiveValidation #StateManagement #GraphExecution Zen Koan Explanation: The code uses `interrupt()` to pause execution and wait for user input, validating it in a loop until a positive integer is received—mirroring the koan's imagery of an "interrupt" that "gobbles" prompts and "spits out" valid ages while remaining "forever hungry" for correct input. This pattern embodies persistent validation, where the graph patiently waits (like a hungry entity) until the right "number" is provided.
