This user-agent information is sent along with API calls to allow the receiving service to do analytics on which versions of Python and Google libraries are being used. Args: python_version (str): The Python interpreter version, for example, ``'3.9.6'``. grpc_version (Optional[str]): The gRPC library version. api_core_version (str): The google-api-core library version. gapic_version (Optional[str]): The sversion of gapic-generated client library, if the library was generated by gapic. client_library_version (Optional[str]): The version of the client library, generally used if the client library was not generated by gapic or if additional functionality was built on top of a gapic client library. user_agent (Optional[str]): Prefix to the user agent header.
