Hello @sdimovv, Thank you once again for creating this issue and as per the current implementation, the actions/setup-python action does not support reading multiple Python versions from a .python-version file. Instead, we should specify multiple versions directly in the yaml configuration under the python-version parameter like below as per this documentation.
uses: actions/setup-python@v5
with:
python-version: |
3.8
3.9
3.10
Adding support to list multiple versions from a python-version-file that is expecting from this issue can be implemented as a feature request.
