setuptools

Installation and Setup

Install it from the Python Package Index (PyPI) into a virtual environment:

• Windows
• Linux + macOS

PS> py -m pip install setuptools

$ python -m pip install setuptools

Key Features

• Acts as a PEP 517 build backend and supports PEP 621 project metadata in pyproject.toml.
• Discovers packages automatically and supports a src/ layout through simple configuration.
• Defines console scripts and plugin entry points that expose commands and extensibility hooks.
• Includes package data and supports extras, environment markers, and optional dependencies.
• Builds pure Python and compiled extension modules and integrates with common build tools.

Usage

A modern project declares its build system and metadata in pyproject.toml:

[build-system]
requires = ["setuptools", "wheel"]
build-backend = "setuptools.build_meta"

[project]
name = "package-name"
version = "0.1.0"
description = "Example package"
readme = "README.md"
requires-python = ">=3.10"
dependencies = ["requests>=2.32"]

# ...

Install your project in editable mode during development:

$ python -m pip install -e .
