How to use the pylxd.operation.Operation.wait_for_operation function in pylxd

def _set_state(self, state, timeout=30, force=True, wait=False):
        response = self.api.state.put(json={
            'action': state,
            'timeout': timeout,
            'force': force
        })
        if wait:
            Operation.wait_for_operation(
                self.client, response.json()['operation'])
            self.sync()

def create(cls, client, config, wait=False):
        """Create a new container config."""
        response = client.api.containers.post(json=config)

        if wait:
            Operation.wait_for_operation(client, response.json()['operation'])
        return cls(client, name=config['name'])

method does not enforce that constraint, so a LXDAPIException may be
        raised if this method is called on a running container.

        If wait=True, an Image is returned.
