How to Create Python Package and Upload to PyPi

Create your own Python Package and upload to PyPi to share with other. Or at least in this case the test.pypi index. Adding the licence the readme and the setup.py file plus you package we take you through it all and download in another python project.
Create new project
pip install --upgrade pip
pip install twine wheel setuptools
create README.md
my_test_project
This is a simple test project
create LICENSE.txt

create setup.py
from setuptools import setup, find_packages
from os import path
working_directory = path.abspath(path.dirname(__file__))
with open(path.join(working_directory, 'README.md'), encoding='utf-8') as f:
long_description = f.read()
setup(
name='my_test_project_am', # name of packe which will be package dir below project
version='0.0.1',
url='github.com/yourname/yourproject',
author='The Urban Penguin',
author_email='[e-mail]',
description='Simple test package',
long_description=long_description,
long_description_content_type='text/markdown',
packages=find_packages(), auto_discover packages
install_requires=[],
)
Now create the package to match name in setup.py
Now in package create module with function
project-
- setup.py
- README.md
- LICENSE.txt
- my_test_project_am/
- test.py
- add_two_numbers()
Now create sdist (source dist) and bdist (Binary dist) files
To distribute your Python packages via PyPI (Python Package Index), it's common practice to generate both source distribution (sdist) and built distribution (often a wheel, which is a kind of binary distribution).
Here's why you might want to create both types:
Source Distribution (sdist):
A source distribution contains your source code and a setup.py file. This allows end-users to view and build your project from its source code. This is useful for distributing to other developers, who may want to modify your code, learn from it, or who may be running environments that require compilation (some C extensions, for example). A source distribution can be created using the python setup.py sdist command.
Built Distribution (wheel):
A wheel is a Python built distribution that is fast to install, doesn't require the execution of setup.py on the client's side, and doesn't require compilers since it's precompiled. Wheel packages can be installed with pip without building any source code. This is useful for end-users who only want to install and use your package without going through the build process. A wheel distribution can be created using the python setup.py bdist_wheel command.
Ideally, when publishing a package to PyPi, you'd upload both source (sdist) and built (wheel) distributions. This is because not all platforms or versions of Python out there may be compatible with a pre-built wheel file, but theoretically, they could all install from the source distribution. On the other hand, wheel is faster and easier to install, which is why it's preferred when compatible
python setup.py sdist bdist_wheel
check for errors or warning with twine
twine check dist/*
upload to testpypi ( you'll need API or username and password depending on your system )
twine upload --repository-url test.pypi.org/legacy/ dist/*
create new project
pip install --index-url test.pypi.org/simple/ my-test-project-am

[@DefAir_]

The best video on this topic, thank you so much, you helped me a lot.

[@theurbanpenguin]

Glad it was helpful!

[@anisdhouieb9918]

what is the AI tool you're using with pycharm ? seems like it"s reading your thoughts 😅

[@theurbanpenguin]

it is the ai assistant built into the latest version of PyCharm
