# Python Quickstart Tutorial: Building an A2A Agent Welcome to the Agent2Agent (A2A) Python Quickstart Tutorial! In this tutorial, you will explore a simple "echo" A2A server using the Python SDK. This will introduce you to the fundamental concepts and components of an A2A server. You will then look at a more advanced example that integrates a Large Language Model (LLM). This hands-on guide will help you understand: - The basic concepts behind the A2A protocol. - How to set up a Python environment for A2A development using the SDK. - How Agent Skills and Agent Cards describe an agent. - How an A2A server handles tasks. - How to interact with an A2A server using a client. - How streaming capabilities and multi-turn interactions work. - How an LLM can be integrated into an A2A agent. By the end of this tutorial, you will have a functional understanding of A2A agents and a solid foundation for building or integrating A2A-compliant applications. ## Tutorial Sections The tutorial is broken down into the following steps: 1. **[Introduction (This Page)](./1-introduction.md)** 2. **[Setup](./2-setup.md)**: Prepare your Python environment and the A2A SDK. 3. **[Agent Skills & Agent Card](./3-agent-skills-and-card.md)**: Define what your agent can do and how it describes itself. 4. **[The Agent Executor](./4-agent-executor.md)**: Understand how the agent logic is implemented. 5. **[Starting the Server](./5-start-server.md)**: Run the Helloworld A2A server. 6. **[Interacting with the Server](./6-interact-with-server.md)**: Send requests to your agent. 7. **[Streaming & Multi-Turn Interactions](./7-streaming-and-multiturn.md)**: Explore advanced capabilities with the LangGraph example. 8. **[Next Steps](./8-next-steps.md)**: Explore further possibilities with A2A.
