SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Packaging Python code for reuse, installation, and release can be confusing and inconsistent. This Skill gives you a clear path to structure projects correctly, define metadata, and produce installable artifacts for Python libraries and command-line tools.

Core Features & Use Cases

  • Source-layout and flat-layout project structures for different packaging needs.
  • Modern pyproject.toml setup with build backend, dependencies, optional extras, and entry points.
  • Guidance for editable installs, wheel and source distribution builds, and PyPI publishing workflows.
  • Advanced patterns for data files, namespace packages, C extensions, semantic versioning, and test installation.
  • Use cases include publishing a reusable library, shipping a CLI tool, or preparing a project for automated releases.

Quick Start

Use this Skill to turn a Python codebase into a distributable package by choosing a project layout, writing packaging metadata, and preparing it for build and publication.

Frequently Asked Questions about python-packaging

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I configure pyproject.toml for a Python package?▼

Configuring pyproject.toml involves specifying your build backend, core dependencies, optional extras, and entry points. This modern approach replaces setup.py and structures your project metadata for building installable wheel and source distribution artifacts.

What's the best way to structure a Python project for PyPI publishing?▼

Structuring a Python project for PyPI publishing requires choosing between a source-layout or flat-layout based on your needs. Correct structuring ensures proper package discovery, enabling smooth builds of wheel and source distribution artifacts for release.

How does a build backend work when creating Python wheels?▼

A build backend processes your pyproject.toml metadata and source code to create distributable Python wheels. Selecting the right backend dictates how dependencies are resolved, how package discovery works, and how the final installation artifact is assembled.

Can I ship a CLI tool as a Python package with entry points?▼

You can ship a CLI tool as a Python package by defining entry points in your pyproject.toml configuration. This maps command-line script names to specific Python functions, enabling the automatic creation of executable scripts upon package installation.

How do I handle namespace packages and data files in Python packaging?▼

Handling namespace packages and data files in Python packaging requires applying advanced structural patterns during project setup. This ensures correct package discovery, proper distribution, and the reliable inclusion of non-code resources within your build artifacts.

Do I need editable installs and test installation for Python library development?▼

Editable installs and test installation are essential for Python library development to verify packaging integrity locally. Editable installs allow immediate code changes without reinstallation, while test installation validates dependency declaration and artifact builds.
