Getting Started


To install Pizco you need to to install PyZMQ following the instructions here. If you are having trouble at this step, a few Python distributions like EPD and Anaconda have PyZMQ preinstalled.

Then install, Pizco using pip or easy_install:

$ easy_install pizco


$ pip install pizco

Basic usage

Consider the:

from myproject import Robot

robot = Robot()

robot.age = 28

Pizco provides two classes t:

  • Server: wraps an object and exposes its attributes via a ZMQ socket.
  • Proxy: connects to a server, redirects attribute request to it, and collect the response.

Creating a Server is quite simple, just instantiate a Server using the object as the first parameter:

# This is your stuff
from myproject import Robot

from pizco import Server

server = Server(Robot())

If no endpoint is given, the server will bind to a random tcp port.

You can specify the endpoint with the second argument:

server = Server(Robot(), 'tcp://')

Any valid ZMQ endpoints is valid:

  • inproc: local in-process (inter-thread) communication transport

    example: inproc://robbie-the-robot

  • ipc: local inter-process communication transport

    example: ipc://robbie-the-robot

  • tcp: unicast transport using TCP

    example: tcp://

In the client side, you need to create a proxy:

from pizco import Proxy

robot = Proxy('tcp://')

and now you can use the proxy as if it was the actual object:

robot.age = 28

Notice that the only needed change was to the initialization code.

Remote exceptions

Exception in the served object are caught remotely and re-raised by the proxy and therefore the following code:

    robot.age = input()
except ValueError as ex:
    print('That is not a valid age for the robot')

will work the same way if the robot is the actual object or just a Proxy to it.


The remote traceback is not propagated the proxy in the current version of Pizco.
