Claude in Action: A Practical Guide to Building AI Applications with Python - Second Edition

Learn Claude and Build Intelligent AI Applications with Python

Generative AI is transforming how people work, analyze information, and build software. Claude, developed by Anthropic, combines powerful capabilities for writing, research, document analysis, multimodal interaction, code generation, and AI application development.

Claude in Action: A Practical Guide to Building AI Applications with Python - Second Edition provides a practical, hands-on path from AI and generative AI fundamentals to building and deploying Claude-powered applications. You will learn how Claude works, use the Claude web interface and Projects, analyze documents and images, and develop effective prompts using fundamental, advanced, and Claude-specific prompting techniques.

For developers, the book covers the Anthropic SDK, Claude API, Messages API, Python code generation, debugging, refactoring, testing, documentation, FastAPI, and Streamlit. You will progress into embeddings, vector databases, semantic search, Retrieval-Augmented Generation (RAG), the Model Context Protocol (MCP), and AI agents with planning, reasoning, memory, and tool use.

The book also covers security, responsible AI, prompt injection, data privacy, governance, performance and cost optimization, logging, monitoring, Docker deployment, and scaling. Enterprise use cases demonstrate how Claude can be applied across industries, while hands-on projects bring the concepts together through complete Python applications.

Source code for the hands-on examples and projects is available on GitHub. QR codes included in the book provide convenient access to the corresponding GitHub source code, making it easy to follow along, experiment with the examples, and extend the projects.
