是否使用os.walk()将目录中的所有.txt文件移动到新文件夹？

import os
import shutil

def move_txt_files(source_dir, destination_dir):
    for root, dirs, files in os.walk(source_dir):
        for file in files:
            if file.endswith(".txt"):
                source_file = os.path.join(root, file)
                destination_file = os.path.join(destination_dir, file)
                shutil.move(source_file, destination_file)

# 调用示例
source_directory = "/path/to/source/directory"
destination_directory = "/path/to/destination/directory"
move_txt_files(source_directory, destination_directory)
