Say hello!

Python Package Example

This repository contains a basic python package example with the aim of showing how a good python package should look like.

Install:

pip install helloworld-mkmenta

Install locally:

git clone https://github.com/mkmenta/python-package-example.git
cd python-package-example
pip install -e .

Usage

You will find an usage example here.

Documentation

This project has a documentation in readthedocs.io generated using sphinx: documentation.

Find the tutorial on how it was created here.

Developing

To install the package along with the tools you need to develop it run the following (local installation with the "dev" extras:

git clone https://github.com/mkmenta/python-package-example.git
cd python-package-example
pip install -e ."[dev]"

If you are developing, you should run pip install -e . every time you change setup.py or the dependencies etc. to make sure that everything works.

A note about requirements

The requirements needed to run the package should go in the install_requires argument of setup() in the setup.py.

The requirements needed to develop the package should go in the extras_require argument dict (under the "dev" key) of setup() in the setup.py.

This is preferred to a requirements.txt file, because this is code and it can be understood directly during the installation of the package itself.

The requirements.txt should be used to recreate enviroments with specific versions (e.g.requests==2.22.0), not to share software.

Building and distribution

Build without installi i.e. build wheel:

python3 setup.py bdist_wheel

Source distribution:

python3 setup.py sdist

For the source distribution, remember to:

• Check out the warnings of python3 setup.py sdist.
• Check that every file from the repo is packed in the tar file (tar tzf dist/helloworld-X.X.X.tar.gz) as written in the MANIFEST.in. A useful tool is check-manifest.

Uploading to PyPI

python3 setup.py bdist_wheel sdist
twine upload dist/*

Code format checks and tests (GitHub Actions for continuous integration)

In order to check the code format and test it, this project runs a GitHub action defined in .github/workflows/main-action.yml.

You can check the execution of this action here.

This allows blocking any merge of a pull request if the code is not correcly formatted or tests are not passing. In order to do that you can go to Settings -> Branches -> Add rule

Other useful stuff

• This repo is prepared for PyCharm and it has some run configurations (in .idea/runConfigurations).
