Multiple Python versions from version-file in one environment - #647

Hi @viccie30, Thank you for your contribution to the setup-python action!
We appreciate your efforts in proposing this feature. However, we have reviewed the changes and found that they will break when the python-version-file input is set to pyproject.toml. Attached is a screenshot for your reference. According to the official Poetry documentation, the pyproject.toml file only supports specifying a single Python version constraint or range, not multiple discrete versions.
For example:

[tool.poetry.dependencies]
python = ">=3.6,<4.0"

This specifies a range of acceptable Python versions but does not list multiple discrete versions. You can find more details in the official Poetry documentation: Poetry Documentation - Specifying Dependencies.

Hi @viccie30,
Just a gentle reminder. Do you have any concerns or updates regarding the previous discussion?

I don't, mostly because I cannot remember what I was trying to do two years ago, when I opened this pull request. I have not used this action for some 18 months, I think, so feel free to use or discard this as you think best.

Hi @viccie30, Thank you for your response. Since it is not compatible with the official specifications, we will be closing this pull request. If you have any further questions or concerns, please feel free to reach out and encourage you to continue sharing feedback as we strive to improve the action.
