####################################################################################
## This workflow automates the build and release process for Valispace            ##
## Python API. Triggered on pushes to the master branch, the workflow             ##
## sets up Python environments for multiple versions (3.9),                       ##
## displays the Python version, installs Twine for package management, builds     ##
## the project using python setup.py bdist_wheel, and releases the distribution   ##
## files to  PyPI using Twine.                                                    ##
