Additional Information

Windows is interpreting ring.py as an EXE instead of expanding it using python3.exe. This appears to be a Go limitation on Windows:

"Unlike the “system” library call from C and other languages, the os/exec package intentionally does not invoke the system shell and does not expand any glob patterns or handle other expansions, pipelines, or redirections typically done by shells."
