ZMQ Req/Rep Example

zmq_client_req.py

import zmq  # Client
sock = zmq.Context().socket(zmq.REQ)
sock.connect("tcp://127.0.0.1:10000")
sock.send('0')
print(sock.recv())  # Prints "1"

zmq_server_rep.py

import zmq  # Server
sock = zmq.Context().socket(zmq.REP)
sock.bind("tcp://127.0.0.1:10000")
print(sock.recv())  # Prints "0"
sock.send('1')

In Python 3, this should use send_string or it should send b'0' and 'b'1'`
