LangGraph for Beginners: Build AI Agents & Workflows with Python

Learn LangGraph from scratch in Python: type annotations, core elements, five graph-building agents with exercises (single node, multiple inputs, sequential, conditional, looping), then AI agents: a simple bot, a chatbot with memory, a ReAct agent, a drafter agent with human-in-the-loop and a RAG agent.
