- Highlight real-world use cases — from automating email triage to generating weekly analytics reports.
2. Prerequisites & Tooling Setup
- List required tools: Python 3.10+, an OpenAI API key (or Anthropic), and a code editor (VS Code recommended).

openai,langchain,python-dotenv, andpydantic. - Show how to securely store your API key in a
