Publishing my 1st Python Package to PyPI

I own a easy-to-remember domain router.hk for years. I develop a IP address lookup which helps Linux & network administrators and end users. Last week, I develops a newer version of API which can return IP address by a simply curl command.

This week, I try to develop a Python package for it and upload to PyPI (Python Package Index). Developing a python package requires better file structure and additional files.

PyPI: https://pypi.org/project/routerhk/
GitHub: https://github.com/routerhk/routerhk

File Structure

routerhk/
├── routerhk/
│ ├── init.py
│ └── routerhk.py
├── tests/
│ └── test_routerhk.py
├── setup.py
├── README.md
├── requirements.txt
└── LICENSE

1. My package has the above structure.
2. Develop a class RouterHk in routerhk.py, call it from routerhk/init.py, test the class and functions manually.
3. Write a test_routerhk.py, I use unittest.
   1. python -m unittest tests/test_routerhk.py
   2. I may change it back to pytest later.
4. Refer to other python packages to create setup.py which lets PyPI
   1. pip install setuptools wheel
   2. python setup.py sdist bdist_wheel
   3. pip install .
   4. Test the installed local python package from other directory.
5. Upload to PyPI
   1. pip install twine
   2. twine upload dist/*
   3. Input API Token and upload the package to PyPI.

My PyPI account was created on 2016. I creates a API token on pypi.org and use it to upload the package.

Example code using routerhk:

from routerhk import RouterHk
r = RouterHk()
r.get_ip()
r.ip_address
