The same issue occurs if multiple versions of python are specified in the
.python-versionfile.v-priya-kinthali commentedon Sep 27, 2024
Hello 👋,
@nitrocode , The
setup-pythonaction does not currently support comments within the.python-versionfile, which is causing the error you encountered. We appreciate you bringing this to our attention and will consider incorporating comment support in future enhancements. In the meantime, please ensure that the.python-versionfile contains only the version number without any comments.@olivierlefloch , Regarding specifying multiple versions in the
.python-versionfile, there is an existing feature request to support listing multiple versions. We will consider this for future updates.Thank you both for your inputs and helping us improve the

Thank you for bringing up this feature request and outlining the scenario involving comments within the .python-version file. We are pleased to inform you that the relevant features and improvements have been implemented as part of PR #787. With this update, the action now properly ignores comment lines in the version file, ensuring only valid Python versions are processed.
As this feature request is now addressed, we are closing this issue. If you encounter any further issues or have additional suggestions, please feel free to open a new issue.
