从Python CLI程序中智能地启动默认编辑器？

import subprocess
import os

def open_default_editor(file_path):
    if os.name == 'nt':  # Windows
        os.startfile(file_path)
    elif os.name == 'posix':  # Unix
        subprocess.call(('xdg-open', file_path))
    else:
        raise OSError(f"Unsupported operating system: {os.name}")

file_path = "path/to/your/file.txt"
open_default_editor(file_path)
