ZeroMQ: how to find which port a PAIR socket is using?

Question

Is there a way to see which port a ZeroMQ (actually pyzmq) port is connected to after connecting?
For example...

import zmq
context = zmq.Context()
socket = context.socket(zmq.PAIR)
port = socket.bind_to_random_port("tcp://*")
# some other code that might change that binding
actual_port = socket.which_port???()  # (this is what I want)

Could not find in documentation or other forums. Would have helped save me some debugging time!

```

Answer 1

The .bind_to_random_port() method will automatically pick a port to bind to and the return will contain the port it bound too. The return is an int.
