Setuptools is the official build system and packaging library for Python, enabling developers to build, package, and distribute Python projects as wheels and sdists. It extends distutils and supports modern pyproject.toml-based configuration.

Use cases

• build a wheel for my python package
• define package metadata in pyproject.toml
• package and publish my library to pypi
• declare dependencies and entry points for a python project
• build an sdist for distribution
• migrate from distutils to a modern build backend
• install a package in editable/development mode

When to choose

• you are packaging a Python library or application for distribution on PyPI
• you need a mature, widely supported build backend for pyproject.toml
• you need editable installs, entry points, or package data handling

When to avoid

• you are building a non-Python project
• you only need a modern alternative like hatchling, flit, or poetry-core and have no legacy setuptools constraints
• you need a dependency manager rather than a build system
