from google.protobuf.empty_pb2 import Empty # Create an empty message object empty_msg = Empty() # Serialize the message object to bytes serialized_msg = empty_msg.SerializeToString() # Parse a bytes object into an empty message object deserialized_msg = Empty.FromString(serialized_msg)In the above example, we import the `Empty` message from the `google.protobuf.empty_pb2` package. We then create an empty message object, serialize it to bytes, and parse the bytes back into a message object. This package library is part of the Google Protocol Buffers library for Python.
