## Use Multiple Python Versions

For some jobs, it can be relevant to use multiple Python versions, such as:

- Test jobs: `py-unittest`, `py-pytest`, `py-nosetest`

- `py-publish` jobs (especially if you're not generating a pure Python package)

This setup is done by defining the PYTHON_IMAGE variable with a parallel/matrix strategy in your .gitlab-ci.yml.

For example, to run py-test jobs using both python:3.13-slim and python:3.12-alpine:

```yaml

py-pytest:

  parallel:

    matrix:

      - PYTHON_IMAGE: python:3.13-slim

      - PYTHON_IMAGE: python:3.12-alpine

```

If your tests cannot be executed concurrently due to shared resources (e.g. database access), you can use the `resource_group` feature to limit parallel execution:

```yaml

py-pytest:

  parallel:

    matrix:

      - PYTHON_IMAGE: python:3.13-slim

      - PYTHON_IMAGE: python:3.12-alpine

  resource_group: db_access_tests

```
