python 判断字符串是否为（或包含）IP地址

下面是某个字符串是否为IP地址
import re

def isIP(str):
    p = re.compile('^((25[0-5]|2[0-4]\d|[01]?\d\d?)\.){3}(25[0-5]|2[0-4]\d|[01]?\d\d?)$')
    if p.match(str):
        return True
    else:
        return False
myStr = "10.69.36.95"
if isIP(myStr):
    print(myStr,"it is a IP!")
else:
    print(myStr, "it is not a IP!")

下面是某个字符串是否包含IP地址（两种方法分别进行判断）

import re
def ip_exist_two(one_url):
    compile_rule = re.compile(r'(?<![\.\d])(?:\d{1,3}\.){3}\d{1,3}(?![\.\d])')
    match_list = re.findall(compile_rule, one_url)
    if match_list:
        print (match_list)
    else:
        print('missing................')
def ip_exist_one(one_url):
    compile_rule = re.compile(r'\d+[\.]\d+[\.]\d+[\.]\d+')
    match_list = re.findall(compile_rule, one_url)
    if match_list:
        print( match_list)
    else:
        print ('missing................')
if __name__ == '__main__':
    ip_list = ['http://101.23.45.67/sd/sd.html','http://www.baidu.com',
    'http://34.54.65.3/dsdfjkk.htm','http://dhj.fdjjd.com/78078979/dsdfjkk.htm']
    for one_url in ip_list:
        ip_exist_one(one_url)
    print ('****************************************************')
    for one_url in ip_list:
        ip_exist_two(one_url)
