If you can use the **latest versions of Python**, use the examples for the latest version, those will have the **best and simplest syntax**, for example, "**Python 3.10+**".

#### List

For example, let's define a variable to be a `list` of `str`.

//// tab | Python 3.9+

    - name: Report list of changed files

        echo Changed files: ${{ steps.get_file_changes.outputs.files }}

      with:
        python-version: "3.9"
