Getting started with Claude Code — local Python execution with AI assistance.
A set of three small, self-contained Python projects showing how Claude Code goes from "hello world" to a multi-file data pipeline, working directly on real files in your project instead of just chatting about code.
- Node.js (required to install Claude Code)
- An Anthropic API key (or a Claude subscription that includes Claude Code)
- Python 3.9+
npm install -g @anthropic-ai/claude-code
claudeThen run claude from inside any project folder to start a session.
| Project | What it covers |
|---|---|
| 01-hello-world | Your first Claude Code script — sanity-check the toolchain |
| 02-csv-analysis | Read a CSV and compute summary statistics with pandas |
| 03-data-pipeline | Multi-step pipeline: load → clean → report, across multiple files |
Claude Code lets you work with real files, not just chat. Every project here was built by asking Claude Code to write, run, and fix actual scripts in this repo — the same loop you'd use on a production codebase.
