For the final week of our Python + AI series, we're focusing on the technologies needed to build AI agents, starting with the foundation: tool calling (also known as function calling).

We will define our tool call definitions using both JSON schema and Python function definitions, and send those tool definitions to the LLM. We will discover how to properly handle tool call responses from LLMs, enable "parallel" tool calling, and iterate over multiple tool calls.

It is absolutely essential to understand tool calling before diving into agents, so do not miss this foundational session.
