同一目录中的文本文件中具有regex的Grep ip地址

import os
import re

def grep_ip_addresses(directory):
    ip_addresses = []
    file_list = os.listdir(directory)
    for file_name in file_list:
        if file_name.endswith(".txt"):

                ip_pattern = r'\b(?:\d{1,3}\.){3}\d{1,3}\b'  # 此处为简单的IP地址匹配正则表达式
                matches = re.findall(ip_pattern, content)
                ip_addresses.extend(matches)
    return ip_addresses

directory = "指定目录路径"
