PyZMQ Documentation#

PyZMQ is the Python bindings for ØMQ. This documentation currently contains notes on some important aspects of developing PyZMQ and an overview of what the ØMQ API looks like in Python. For information on how to use ØMQ in general, see the many examples in the excellent ØMQ Guide, all of which have a version in Python.

PyZMQ works with Python 3 (≥ 3.7), as well as PyPy via CFFI.

Please don’t hesitate to report pyzmq-specific issues to our tracker on GitHub. General questions about ØMQ are better sent to the ØMQ tracker or mailing list.

Changes in PyZMQ

Supported LibZMQ#

PyZMQ aims to support all stable (≥ 3.2.2, ≥ 4.0.1 ) versions of libzmq. Building the same pyzmq against various versions of libzmq is supported, but only the functionality of the linked libzmq will be available.


libzmq 3.0-3.1 are not supported, as they never received a stable release.

Binary distributions (wheels on PyPI) of PyZMQ ship with the stable version of libzmq at the time of release, built with default configuration, and include CURVE support provided by libsodium. For pyzmq-26.0.3, this is 4.3.5.

Using PyZMQ#

To get started with ZeroMQ, read the ZeroMQ guide, which has every example implemented using PyZMQ.

You can also check out the examples in the pyzmq repo.
