nit
I think it is normal to indent the continuation in the argument section. Also capitalize the first letter of each section and add period instead of comma at the end of the section.

def export_table(service, cloud_storage_path, projectId, datasetId, tableId,
                 num_retries=5):
    """
    Starts an export job

    Args:
        service: Initialized and authorized bigquery google-api-client object.
        cloud_storage_path: Fully qualified path to a Google Cloud Storage
            location (e.g. gs://mybucket/myfolder/).

    Returns: An extract job resource representing the job. See
        https://cloud.google.com/bigquery/docs/reference/v2/jobs
    """
    pass

The docstring still has wrong indentations.

It should be as follows:

def export_table(service, cloud_storage_path,
                 projectId, datasetId, tableId,
                 export_format="CSV",
                 num_retries=5):
    """
    Starts an export job.

    Args:
        service: Initialized and authorized bigquery
            google-api-client object.
        cloud_storage_path: Fully qualified
            path to a Google Cloud Storage location.
            e.g. gs://mybucket/myfolder/
        export_format: Format to export in;
            "CSV", "NEWLINE_DELIMITED_JSON", or "AVRO".

    Returns: An extract job resource representing the
        job, see https://cloud.google.com/bigquery/docs/reference/v2/jobs
    """
  • Use period at the end of the clause
  • Use capitalized first letter
  • Correct indentation (continuation line should have deeper indent, for example, the second line for the "service" argument should have deeper indentation)
