-Using **python-version** output, it's possible to get the precise Python or PyPy version installed by the action. This output is useful when the input `python-version` is given as a range (e.g. 3.8.0 - 3.12.0, 3.x, * ), but down the line you need to operate (such as in an `if:` statement) with the exact installed version (e.g. 3.12.0).
