将所有子文件夹中的所有*.mp4文件移动到另一个指定的文件夹

import os
import shutil

def move_mp4_files(source_folder, destination_folder):
    for root, dirs, files in os.walk(source_folder):
        for file in files:
            if file.endswith(".mp4"):
                source_path = os.path.join(root, file)
                destination_path = os.path.join(destination_folder, file)
                shutil.move(source_path, destination_path)

# 调用示例
source_folder = "/path/to/source/folder"
destination_folder = "/path/to/destination/folder"
move_mp4_files(source_folder, destination_folder)
