[Python知识库]上传python包到PyPi（含本人实列）

最近搞机器学习，很多东西都在重复做。重复的代码可以使用函数，重复的调用就要写py文件了。每次导入py又很麻烦，怎么才能省事呢？于是我想到了pip，言归正传，下面分布介绍pip。

创建项目工程或者独立py文件

1.文件不允许在ifmain以外的地方出现print函数以及控制运行的函数数量
如果非要这么做，请使用以下代码：

if __name__ == "__main__":
    your example code goes here

2.项目结构应该为如下标准（名字仅供参考）：

/packaging_tutorial
 /example_pkg
  __init__.py

其中，packaging_tutorial 是一个文件目录，example_pkg 是一个你希望上传的 Python 包。
3.init.py文件Import设置访问的类
4.包文件夹之外需要放置的文件:
setup.py
setup.cfg
LICENSE.txt
README.md (optinal but highly recommended)

sertup写法：

setup.py文件包含关于PyPi需要的包的信息，比如它的名称、描述、当前版本等。复制并粘贴以下代码，并替换从你匹配内容:

from distutils.core import setup
setup(
  name = 'YOURPACKAGENAME',         # How you named your package folder (MyLib)
  packages = ['YOURPACKAGENAME'],   # Chose the same as "name"
  version = '0.1',      # Start with a small number and increase it with every change you make
  license='MIT',        # Chose a license from here: https://help.github.com/articles/licensing-a-repository
  description = 'TYPE YOUR DESCRIPTION HERE',   # Give a short description about your library
  author = 'YOUR NAME',                   # Type in your name
  author_email = 'your.email@domain.com',      # Type in your E-Mail
  url = 'https://github.com/user/reponame',   # Provide either the link to your github or to your website
  download_url = 'https://github.com/user/reponame/archive/v_01.tar.gz',    # I explain this later on
  keywords = ['SOME', 'MEANINGFULL', 'KEYWORDS'],   # Keywords that define your package best
  install_requires=[            # I get to this in a second
          'validators',       # 可以加上版本号，如validators=1.5.1
          'beautifulsoup4',
      ],
  classifiers=[
    'Development Status :: 3 - Alpha',      # Chose either "3 - Alpha", "4 - Beta" or "5 - Production/Stable" as the current state of your package
    'Intended Audience :: Developers',      # Define that your audience are developers
    'Topic :: Software Development :: Build Tools',
    'License :: OSI Approved :: MIT License',   # Again, pick a license
    'Programming Language :: Python :: 3',      #Specify which pyhton versions that you want to support
    'Programming Language :: Python :: 3.4',
    'Programming Language :: Python :: 3.5',
    'Programming Language :: Python :: 3.6',
  ],
)

setup.cfg：

# Inside of setup.cfg
[metadata]
description-file = README.md

点我制作

上传

1.cd 到 setup.py所在的目录
2.现在，我们用下面的命令创建一个source distribution:

python setup.py sdist
twine upload dist/*

说明：
未安装twine运行

pip install twine

提示twine不是内部或外部命令：

python-m twine upload --repository dist/*

可以pip install 你的代码了

实列：

本人的项目结构（没有写的，是上传到pypi自动生成的）：

setup内容：

from distutils.core import setup
setup(
  name = 'TechLearn',         # How you named your package folder
  packages = ['kits'],   # Chose the same as "name"
  version = '1.0',      # Start with a small number and increase it with every change you make
  license='MIT',        # Chose a license from here: https://help.github.com/articles/licensing-a-repository
  description = 'TYPE YOUR DESCRIPTION HERE',   # Give a short description about your library
  author = 'YOUR NAME',                   # Type in your name
  author_email = 'wzzhangzheyuan@163.com',      # Type in your E-Mail
  url = 'https://github.com/GodOn514/TechLearn',   # Provide either the link to your github or to your website
  download_url = 'https://codeload.github.com/GodOn514/TechLearn/zip/refs/heads/main',    # I explain this later on
  keywords = ['SOME', 'MEANINGFULL', 'KEYWORDS'],   # Keywords that define your package best
  install_requires=[            # I get to this in a second
          'validators',       # 可以加上版本号，如validators=1.5.1
          'beautifulsoup4',
      ],
  classifiers=[
    'Development Status :: 3 - Alpha',      # Chose either "3 - Alpha", "4 - Beta" or "5 - Production/Stable" as the current state of your package
    'Intended Audience :: Developers',      # Define that your audience are developers
    'Topic :: Software Development :: Build Tools',
    'License :: OSI Approved :: MIT License',   # Again, pick a license
    'Programming Language :: Python :: 3',      #Specify which pyhton versions that you want to support
    'Programming Language :: Python :: 3.4',
    'Programming Language :: Python :: 3.5',
    'Programming Language :: Python :: 3.6',
  ],
)

包的更新方法很多不一一列举了（以下为简单，但可能出证书问题的方法）

python setup.py sdist
twine upload dist/*
pip install XXX --upgrade
