在python中通过桌面应用程序打开文件

import subprocess

def open_file_with_default_program(file_path):
    try:
        subprocess.run(['open', file_path])  # macOS
    except FileNotFoundError:
        try:
            subprocess.run(['xdg-open', file_path])  # Linux
        except FileNotFoundError:
            try:
                subprocess.run(['start', file_path], shell=True)  # Windows
            except FileNotFoundError:
                print("无法打开文件，请检查操作系统和文件关联设置。")

# 示例用法
file_path = '/path/to/file.txt'
open_file_with_default_program(file_path)
