Python遍历文件，搜索某些字符串，如果找到，则复制其余行并合并到一个组合文件中

import os

def search_and_copy_files(root_dir, search_string, output_file):
    with open(output_file, 'w') as output:
        for root, dirs, files in os.walk(root_dir):
            for file in files:
                file_path = os.path.join(root, file)
                with open(file_path, 'r') as f:
                    lines = f.readlines()
                    for line in lines:
                        if search_string in line:
                            output.writelines(lines)
                            break

root_dir = '/path/to/directory'  # 指定要遍历的根目录
search_string = '要搜索的字符串'  # 指定要搜索的字符串
output_file = '/path/to/output/file'  # 指定输出文件的路径
