如何使用Python正确搜索文件目录以获取具体详细信息

import os

def search_files(directory, extension):
    file_list = []
    for root, dirs, files in os.walk(directory):
        for file in files:
            if file.endswith(extension):
                file_path = os.path.join(root, file)
                file_size = os.path.getsize(file_path)
                file_list.append({
                    'name': file,
                    'path': file_path,
                    'size': file_size
                })
    return file_list

directory = '/path/to/directory'  # 替换为实际的目录路径
extension = '.txt'  # 替换为实际的文件扩展名

result = search_files(directory, extension)
for file in result:
    print(f"文件名: {file['name']}")
    print(f"文件路径: {file['path']}")
    print(f"文件大小: {file['size']} bytes")
    print('---')
