How to see the port of the router you are connected to?

I am trying to make a little/small python script that can find out the port of the router you are connected to. and if the script does not find the port it will do a print(f"port {PORT} not found") is it possible to see what the port that you are connected to or better what ports are open on your router?

You can use socket module to try to connect the port of the router and close the socket after work is done:

import socket
from contextlib import closing

host = '192.168.0.1'
port = 25
with closing(socket.socket(socket.AF_INET, socket.SOCK_STREAM)) as sock:
  if sock.connect_ex((host, port)) == 0:
    print("Port is open")
  else:
    print("Port is not open")

Here it tests with port 25 (just for example, SMTP), you can loop through range of 1 to 65536, turning to a function:

import socket
from contextlib import closing

def check_socket(host, port):
    with closing(socket.socket(socket.AF_INET, socket.SOCK_STREAM)) as sock:
      if sock.connect_ex((host, port)) == 0:
        return True
      else:
        return False

if check_socket('192.168.0.1',25):
  print('Port open')
else:
  print('Port closed')
