Python 利用正则获取一段文本里的ip

import re

# 正则表达式匹配 IP 地址
ip_pattern = r'(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)'


def find_ips(text):
    return re.findall(ip_pattern, text)


# 测试文本
text = """
    Here are some IP addresses:
    192.168.1.1, 255.255.255.255, 256.256.256.256, and 123.45.67.89.
    Another one: 10.0.0.1. Invalid ones: 999.999.999.999, 300.300.300.300.
"""

# 查找文本中的所有 IP 地址
ips = find_ips(text)

# 输出所有找到的 IP 地址
for ip in ips:
    print(ip)

结果：

D:\miniconda3\python.exe D:\gitlab\test_demo\3333.py 
192.168.1.1
255.255.255.255
123.45.67.89
10.0.0.1
