A collection of python utils used by the DPN FinNet
Project description
DPN Python Utils
A collection of python utils used by the DPN.
Target minimum python version: 3.8.x
High-level Design Notes
To be broadly compatible with running in synchronous or asynchronous mode.
The principles behind the modules are to:
- Be dependable and provide least surprise
- Fail safe and raise informative exceptions
- Optimise code for readability and maintainability
- Design for intended eventual backwards compatibility
Major versions of dpn_pyutils releases track major Python versions in general availability

Getting Started
The fastest way to get start is with a pyenv.
With pyenv installed on the system, check the latest version of the target python version.
pyenv update && pyenv install -l | grep 3.8
Install
Install with pip using:
pip install dpn_pyutils
Install manually
Install the target python version into pyenv and set up the virtualenv
pyenv install 3.8.11
pyenv virtualenv 3.8.11 dpn_pyutils
pyenv activate dpn_pyutils
pip install --upgrade pip
pip install -r requirements.txt
Upgrade versions
Upgrading is done by uninstalling the package and installing the upgraded version
pip uninstall dpn_pyutils
pip install dpn_pyutils
Building
Building dpn_pyutils can be done with python 3, setuptools and wheel.
python -m pip install --upgrade build
python -m build
The distribution-ready files will be in the dist/
directory.
Packaging and Distribution
Packaging after changes need the following to be executed:
Update the version number
Edit setup.cfg
and bump the version number
pip freeze > requirements.txt
pip install --upgrade -r requirements.txt
git commit -am"Updated requirements, pyproject and bumping version number for release"
Distribute
python -m twine upload --repository pypi dist/*
