打包项目
简单项目打包结构
packaging_tutorial/
your_project/
__init__.py
setup.py
LICENSE
README.md
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：
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',
)
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：

编写README.md
可以用Markdown书写该项目的说明，如：
# Example Package This is a simple example package. You can use [Github-flavored Markdown](https://guides.github.com/features/mastering-markdown/) to write your content.
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：
dist/ example_pkg_YOUR_USERNAME_HERE-0.0.1-py3-none-any.whl example_pkg_YOUR_USERNAME_HERE-0.0.1.tar.gz

上传包
安装twine：
pip install twine
在项目文件夹，运行命令上次dist文件夹下所有内容：
twine upload dist/*
