PR with a fix: actions/python-versions#339 - I don't think having it in there provides any useful output to the users. Maybe I'm wrong tho!

Hello @mxschmitt,
Thank you for reporting this issue. We will investigate it and get back to you as soon as we have some feedback.

Hello @mxschmitt, We’ve investigated the issue and confirmed that the excessive logging originates from the changes introduced in PR #319, specifically this snippet:

#Print out all files in $PythonArchPath
Write-Host ""Files in $PythonArchPath""
$files = Get-ChildItem -Path $PythonArchPath -File -Recurse
Write-Output $files

This generates over 7,000 lines of logs during the setup process—even when the Python version isn't pre-installed on the runner images.

We’re currently reviewing PR #339 to trim or optimize this output. Going forward, only Python versions built after this change is merged will exclude the verbose logs.

We’ll follow up with updates once the cleanup is implemented.
Please feel free to reach out if you have any further questions or concerns.
