AI agents are programs that can perceive information, decide what to do, and take actions toward a goal. Unlike a simple chatbot that only responds to prompts, an agent can use tools, follow steps, and adapt its behavior based on context. In this tutorial, you’ll build a small weather assistant agent in Python that can answer questions like “What’s the weather in Paris?” by calling a weather API.
