About pyzmq

from the package's own PyPI description — quoted content, verbatim

PyZMQ: Python bindings for ØMQ

This package contains Python bindings for ZeroMQ. ØMQ is a lightweight and fast messaging implementation.

PyZMQ should work with any reasonable version of Python (≥ 3.8), as well as PyPy. PyZMQ supports libzmq ≥ 3.2.2 (including 4.x).

For a summary of changes to pyzmq, see our changelog.

ØMQ 3.x, 4.x

PyZMQ fully supports the stable (not DRAFT) 3.x and 4.x APIs of libzmq, developed at zeromq/libzmq. No code to change, no flags to pass, just build pyzmq against the latest and it should work.

Documentation

See PyZMQ's Sphinx-generated documentation on Read the Docs for API details, and some notes on Python and Cython development. If you want to learn about using ØMQ in general, the excellent ØMQ Guide is the place to start, which has a Python version of every example. We also have some information on our wiki.
