Multiples sockets TCP listening in the same PORT Python

I stablish a TCP connection with a host and my machine is listening in the port X. Can I create new sockets which listen in the same port? I am developing in Python, I think that the language is not a issue, but one friend is developing in C and can do it and I can't. It says me that the port is already in use when I want to do the bind. This is my connection code:

sock = socket(AF_INET, SOCK_STREAM)
list_sock.bind((myIp,myPort))
list_sock.connect((dstAddress,dstPort))

Thanks!

Two sockets cannot listen on the same port, so no. – Frédéric Hamidi Oct 30 '13 at 15:28
I though that, but since my friend can do it... – Alvaro Garcia de la Villa Oct 30 '13 at 15:30
Are you sure your friend is not binding sockets to the same port on different interfaces? – Frédéric Hamidi Oct 30 '13 at 15:36

Maybe your friend is using UDP rather than TCP? It is possible to have multiple sockets receive on the same UDP port (via SO_REUSEADDR and SO_REUSEPORT), but not with TCP. – Jeremy Friesner Oct 30 '13 at 15:44
you cannot listen on the same port.. but you can accept multiple requests on the same port by spinning out threads to handle each incoming request.. – Harichandan Pulagam Dec 07 '14 at 01:07
