Python Development Setup
Opinionated, production-ready Python development stack. No choices to make - just use this.
When to Use
- Starting a new Python project
- Modernizing an existing project (migrating from pip/poetry/mypy/black/flake8)
- Setting up linting, formatting, type checking, or testing
- Creating a Justfile for project commands
- Configuring pyproject.toml as the single source of truth
The Stack
