pyudev – pure Python libudev binding

pyudev 0.17 (Changelog, installation)

pyudev is a LGPL licenced, pure Python 2/3 binding to libudev, the device and hardware management and information library of Linux.

Almost the complete libudev functionality is exposed. You can:

  • Enumerate devices, filtered by specific criteria (pyudev.Context)
  • Query device information, properties and attributes,
  • Monitor devices, both synchronously and asynchronously with background threads, or within the event loops of Qt (pyudev.pyqt4, pyudev.pyside), glib (pyudev.glib) and wxPython (pyudev.wx).


Thanks to the power of libudev, usage of pyudev is very simple. 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'))

A user guide gives an introduction into common operations and concepts of pyudev, the API documentation provides a detailed reference:
