python-template

Centre for Net Zero's template for Python projects.

Tools:

• Pipenv for dependency management
• Pytest for testing
• Mypy for type checking
• Flake8 for linting
• isort and black for formatting

There are two Github Actions workflows:

• test_and_lint.yaml runs checks on a Ubuntu Github-hosted runner.
• container.yaml runs the same checks but inside a Docker container and pushes images to Google Cloud Platform Artifact Registry.

Secrets configuration

If you want to use the Docker workflow, you need to set the following secrets:

• GCP_ARTIFACT_REGISTRY, e.g. LOCATION-docker.pkg.dev/PROJECT-ID
• GCP_ARTIFACT_REGISTRY_SA_KEY, the key for a service account with the roles to push and pull images.

Python Setup

You need to set up your Python environment first.

1. Clone this repo.
2. Run make setup in your terminal.

In step 2 this will:

• Run pipenv sync --dev to install dependencies.
• cp .env.template .env to create your local .env file - make sure you fill in any blanks.
• Install your local pre-commit environment which will be used to maintain code standards
• Check the tests work by running pipenv run pytest
