Create a Python package

• Go to https://pypi.org and create an account
  • You will need to add your phone
• Create the file /root/.pypirc with the following content:

[pypi]
	username = __token__
	password = YOUR_API_TOKEN

• Create a project:

cd /path/to/store/package
mkdir PROJECT
touch setup.py README.md
cd PROJECT
touch init.py
touch FIRST_MODULE.py

• Inside init.py you must define the modules of the package:

# inside the init.py
from .MODULE_NAME import *

• Now edit the setup.py file:

from setuptools import setup, find_packages
 
with open("README.md", "r", encoding="utf-8") as fh:
	long_description = fh.read()
 
setup(
	  name="YOUR_PACKAGE_NAME",
	  version"VERSION",
	  packages=find_packages(),
	  install_requires=[],
	  author="YOUR_NAME",
	  description="whatever",
	  long_description=long_description,
	  long_description_content_type="text/markdown",
	  url="YOUR_URL"
)

• Install twine: pip3 install twine
• Upload the content: twine upload dist/*
