// This script wraps logic in @azure-tools/extension to resolve
// the path to Python 3 so that a Python script file can be run
// from an npm script in package.json.  It uses the same Python 3
// path resolution algorithm as AutoRest so that the behavior
// is fully consistent (and also supports AUTOREST_PYTHON_EXE).
//
// Invoke it like so: "node run-python3.cjs script.py"
