Claude Python Setup

A comprehensive CLAUDE.md template for setting up modern Python development environments with uv, ruff, pytest, and automated tooling. This repository provides a battle-tested configuration that can be used with Claude Code to quickly bootstrap Python projects with best practices.

Overview

This repository contains a complete CLAUDE.md file that automates the setup of a modern Python development environment including:

• uv - Fast Python package manager and dependency resolver
• ruff - Lightning-fast Python linter and formatter
• pytest - Modern testing framework with coverage reporting
• pre-commit - Git hooks for code quality enforcement
• GitHub Actions - Automated CI/CD pipeline
• Makefile - Developer convenience commands

Quick Start

Option 1: Use with Claude Code

1. Copy the CLAUDE.md file to your Python project directory
2. Ask Claude Code to run the setup:
