Python setuptools is a collection of tools and libraries that enable you to package and distribute Python projects. It provides a way to define project metadata, dependencies, and other configuration details, making it easier for developers to share their Python code with others.
Here are some key components and concepts related to Python setuptools:
- setup.py: This is a Python script that contains information about your project, such as its name, version, description, author, and more. It also specifies dependencies and other project-specific settings. You create this file at the root of your project directory.
setuptools
module:setuptools
is a Python library that extends the functionality of Python’s built-indistutils
module. It provides additional features and flexibility for packaging and distribution. You can importsetuptools
in yoursetup.py
script to define the project’s setup configuration.setup()
function: In yoursetup.py
script, you call thesetup()
function provided bysetuptools
to define your project’s configuration. This function takes various keyword arguments that allow you to specify project details, dependencies, entry points, and more. Examplesetup.py
script:
from setuptools import setup, find_packages
setup(
name="myproject",
version="1.0.0",
description="A sample Python project",
author="Your Name",
packages=find_packages(),
install_requires=[
"dependency1",
"dependency2",
],
)
- Entry Points: You can specify entry points in your
setup.py
script. Entry points allow other Python packages to discover and use specific functionality from your project. Common entry points include console scripts and plugins. setuptools
commands:setuptools
provides various command-line tools that you can use to perform tasks like building distributions, installing packages, creating source distributions, etc. Some common commands includesdist
(source distribution),bdist_wheel
(wheel distribution), andinstall
.setup.cfg
: While you can define project configuration in yoursetup.py
script, you can also use asetup.cfg
file to specify some of the same metadata and configuration options. This can make thesetup.py
script cleaner and more focused on the code.
Python setuptools simplifies the process of creating distributable Python packages, making it easier for developers to share their code with others and for users to install and use those packages. It is an essential tool for the Python ecosystem and is commonly used in conjunction with package repositories like PyPI (Python Package Index) for distributing Python packages.
