Parse string with variable length [duplicate]

I think I would choose regex for this. It handles most of your cases, you don't have to care about the surrounding noise like spaces or slashes and you can loop through the result.

import re


def verify_ip(ip_address: str) -> bool:
    ip_segments = ip_address.split('.')
    if len(ip_segments) != 4:
        return False
    for segment in [int(ip_segment) for ip_segment in ip_segments]:
        if not 0 < segment < 255:
            return False
    return True


raw_string = '\"0156165100.000.000.000,111.111.111.111,192.168.1.1.10.15 1 68 3+- 41as asdfvyxcv 10.10.10.10\"'
pattern = r'\d+\.\d+\.\d+\.\d+'
matches = re.findall(pattern, raw_string)
for ip in matches:
    print(f'{ip if verify_ip(ip) else "bad ip"}')

Result:

bad ip
111.111.111.111
192.168.1.1
10.10.10.10
