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.

For the penultimate session of our Python + AI series, we're building AI agents! We'll use many of the most popular Python AI agent frameworks: Langgraph, Semantic Kernel, Autogen, Pydantic AI, and more.

Our agents will start simple and then ramp up in complexity, demonstrating different architectures like hand-offs, round-robin, supervisor, graphs, and ReAct.

Today’s DevSecOps pipelines excel at finding issues, but not at knowing which ones truly matter. Traditional testing tools stop at detection, while real security validation often happens late, manually, and out of band.

In this session, we’ll explore what it means to bring offensive security intelligence into the developer workflow, unifying detection, validation, and remediation in a continuous loop. Using XBOW as an example, we’ll discuss how AI-driven reasoning can help teams move from theoretical findings to proof-backed, fix-verified security that keeps pace with modern development.

You'll learn:

• Why DevSecOps needs real-world validation (not just scanning) to close the loop
• How shifting offensive testing left changes prioritization, collaboration, and velocity
• How AI is reshaping the path from vulnerability discovery to verified remediation
