A small script to get my public IP from my router/modem

get_pubip_from_router.py

import telnetlib

PASSWORD = "admin" # change these two
ADDR = "192.168.1.1"

t = telnetlib.Telnet(host=ADDR)
t.read_until("Password:".encode())
t.write((PASSWORD + "\r\n").encode())
t.read_until("TP-LINK> ".encode())
t.write("show wan status\r\n".encode())
data = t.read_until("TP-LINK> ".encode()).decode()
t.write("exit\r\n".encode())
t.close

for line in data.split("\r\n"):
    if "Ip" in line:
        print(line.split()[-1], end="")
