遍历包含许多文本文件的文件夹，并使用Python3查找与所述特定字符串匹配的字符串

import os
import re

def search_string_in_files(folder_path, search_string):
    for root, dirs, files in os.walk(folder_path):
        for file in files:
            file_path = os.path.join(root, file)
            if file_path.endswith('.txt'):  # 只处理文本文件，可以根据需要修改文件类型
                with open(file_path, 'r') as f:
                    content = f.read()
                    if re.search(search_string, content):
                        print(f"Found match in file: {file_path}")

# 调用示例
folder_path = '/path/to/folder'  # 替换为实际的文件夹路径
search_string = 'specific string'  # 替换为要查找的特定字符串
search_string_in_files(folder_path, search_string)
