    name: main
    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-python@v2
        if: "!endsWith(matrix.python-version, '-dev')"
        with:
          python-version: ${{ matrix.python-version }}
      - uses: deadsnakes/[email protected]
        if: endsWith(matrix.python-version, '-dev')
