pysdbus
pysdbus is a Python wrapper library for DBus inter-process communication. It
uses Python's ctypes module to communicate directly with the sd-bus C API of the
systemd library. Hence, pysdbus only depends on the presence of the
libsystemd.so library and a functional Python interpreter in version 2 or 3.
pysdbus offers three APIs:

pysdbus.llapi is the low-level API and a thin ctypes wrapper around
libsystemd's C API
pysdbus is the main API of this library and provides additional convenience
around the low-level API
pysdbus.dbus aims to provide a programming interface similar to the
well-known dbus-python project

Status
This library is still in an early stage. Many features are still missing but
calling and offering APIs with methods, signals and properties is already
implemented.
pysdbus example
import pysdbus

bus = pysdbus.SystemBus()

obj = bus.getObject("org.freedesktop.DBus", "/org/freedesktop/DBus")

iface = obj.getInterface("org.freedesktop.DBus")

reply = iface.ListNames()

for service in reply:
print(service)

pysdbus.dbus example
ml = MainLoop()

bus = SystemBus()

dbus_obj = bus.get_object("org.freedesktop.DBus", "/org/freedesktop/DBus")

iface = Interface(dbus_obj, "org.freedesktop.DBus")

reply = iface.ListNames()

print(reply)

def prop_changed_cb(sender, destination, path, interface, member):
print("new signal: ", sender, destination, path, interface, member)

bus.add_signal_receiver(prop_changed_cb)

def nameowner_changed_cb(sender, destination, path, interface, member):
print("nameowner changed: ", sender, destination, path, interface, member)

iface.connect_to_signal("NameOwnerChanged", nameowner_changed_cb)

ml.run()
