在文件夹和子文件夹中搜索多个文件

import os

def search_files(directory, file_extensions):
    matched_files = []
    for root, dirs, files in os.walk(directory):
        for file in files:
            if any(file.endswith(ext) for ext in file_extensions):
                matched_files.append(os.path.join(root, file))
    return matched_files

directory = '/path/to/directory'  # 搜索的目录路径
file_extensions = ['.txt', '.csv', '.xlsx']  # 需要匹配的文件扩展名列表

matched_files = search_files(directory, file_extensions)
print(matched_files)
