!!! tip
    The second argument to <a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> is the default value to return.

    If not provided, it's `None` by default, here we provide `"World"` as the default value to use.

Then you could call that Python program:

	// state of the world caches. A volume is considered "in use" as soon as it
	// is added to the desired state of world, indicating it *should* be
	// attached to this node and remains "in use" until it is removed from both
	// the desired state of the world and the actual state of the world, or it
	// has been unmounted (as indicated in actual state of world).
	GetVolumesInUse() []v1.UniqueVolumeName

	// It then updates the actual state of the world to reflect that.
	AttachVolume(logger klog.Logger, volumeToAttach VolumeToAttach, actualStateOfWorld ActualStateOfWorldAttacherUpdater) error

	// VerifyVolumesAreAttachedPerNode verifies the given list of volumes to see whether they are still attached to the node.
	// If any volume is not attached right now, it will update the actual state of the world to reflect that.

	// hits a traceAcquire, it sees that the trace is enabled.
	//
	// Note also that stopping the world is necessary to make sure sweep-related events are
	// coherent. Since the world is stopped and sweeps are non-preemptible, we can never start
	// the world and see an unpaired sweep 'end' event. Other parts of the tracer rely on this.
	stw := stopTheWorld(stwStartTrace)
