如何将文件保存在用户选择的路径中

import tkinter as tk
from tkinter import filedialog

root = tk.Tk()
root.withdraw()  # 隐藏主窗口

file_path = filedialog.asksaveasfilename()  # 打开文件选择器对话框

with open(file_path, 'w') as f:
    f.write('Hello, world!')  # 将文件保存到用户选择的路径中

import argparse

parser = argparse.ArgumentParser(description='Save file to specified path.')
parser.add_argument('path', type=str, help='path to save the file')
args = parser.parse_args()

with open(args.path, 'w') as f:
    f.write('Hello, world!')  # 将文件保存到用户指定的路径中

python save_file.py /path/to/save/file.txt
