I want to find all the ports that are open on my localhost using telnet.
I have set up a server using sockets on port 1234.
I am using the following code to check whether a port is open or not

```
import getpass
import sys
import telnetlib

HOST = "127.0.0.1"
for port in range (1,65535):
    try:
        if(telnetlib.Telnet(HOST,port)):
            print(port)
    except ConnectionRefusedError as err:
        print("connection refused")

```

However I get no output when I run this code.
Appreciate any corrections in the code.Thanks
