其中：
*your_project，是项目文件夹
*setup.py，是告诉setuptools关于包的信息，如名称，版本，包含哪些代码文件夹等。
*LICENSE，文件为该项目的许可协议
*README.md，该项目的说明

====编写setup.py====
一个简单的setup.py如下：
<syntaxhighlight lang="python" line='line'>
import setuptools

with open("README.md", "r") as fh:
long_description = fh.read()

setuptools.setup(
name="example-pkg-YOUR-USERNAME-HERE", # Replace with your own username
version="0.0.1",
author="Example Author",
author_email="author@example.com",
description="A small example package",
long_description=long_description,
long_description_content_type="text/markdown",
url="https://github.com/pypa/sampleproject",
packages=setuptools.find_packages(),
classifiers=[
"Programming Language :: Python :: 3",
"License :: OSI Approved :: MIT License",
"Operating System :: OS Independent",
],
python_requires='>=3.6',
)
</syntaxhighlight>

====编写LICENSE====
编写许可协议，告诉安装该包的用户，他们能如何使用。可以在https://choosealicense.com/ 选择一个协议复制到LICENSE文件中，如下面的 MIT license：

====生成发行包====
*首先确认安装了最新的setuptools和wheel
python3 -m pip install --user --upgrade setuptools wheel
*在setup.py所在文件夹运行下面命令打包：
python3 setup.py sdist bdist_wheel
*生成的发行包位于该文件夹下的dist文件夹，dist文件夹包含两个文件，如：
<nowiki>dist/
