Pyudev

pyudev

pyudev is a LGPL_ licensed, pure Python_ binding for libudev_, the device and hardware management and information library for Linux. It supports almost all libudev_ functionality. You can enumerate devices, query device properties and attributes or monitor devices, including asynchronous monitoring with threads, or within the event loops of Qt, Glib or wxPython.

The binding supports CPython_ 3 and compatible versions of PyPy_. It is tested against udev 151 or newer, earlier versions of udev as found on dated Linux systems may work, but are not officially supported.

Usage

Usage of pyudev is quite simply thanks to the power of the underlying udev library. Getting the labels of all partitions just takes a few lines:

import pyudev context = pyudev.Context() for device in context.list_devices(subsystem='block', DEVTYPE='partition'): ... print(device.get('ID_FS_LABEL', 'unlabeled partition')) ... boot swap system

The website_ provides a detailed user guide_ and a complete API reference_.

Request a New Release

I will be doing regular releases of this project every August and October, shortly after Fedora releases are branched from rawhide.

If you believe an extra release would help you in some way, please file an issue, explaining why you need the new release, and I expect I'll put one up.

Why should you explain why you need the new release? Well, it is helpful to me, because pyudev is not at all part of my regular work, and I tend not to know very much about how it is used these days.
