Example: >>> from google.cloud import dataproc_v1beta2 >>> >>> client = dataproc_v1beta2.AutoscalingPolicyServiceClient() >>> >>> parent = client.region_path('[PROJECT]', '[REGION]') >>> >>> # Iterate over all results >>> for element in client.list_autoscaling_policies(parent): ... # process element ... pass >>> >>> >>> # Alternatively: >>> >>> # Iterate over results one page at a time >>> for page in client.list_autoscaling_policies(parent).pages: ... for element in page: ... # process element ... pass Args: parent (str): Required. The "resource name" of the region or location, as described in https://cloud.google.com/apis/design/resource\_names. - For ``projects.regions.autoscalingPolicies.list``, the resource name of the region has the following format: ``projects/{project_id}/regions/{region}`` - For ``projects.locations.autoscalingPolicies.list``, the resource name of the location has the following format: ``projects/{project_id}/locations/{location}`` page_size (int): The maximum number of resources contained in the underlying API response. If page streaming is performed per- resource, this parameter does not affect the return value. If page streaming is performed per-page, this determines the maximum number of resources in a page. retry (Optional[google.api_core.retry.Retry]): A retry object used to retry requests. If ``None`` is specified, requests will be retried using a default configuration. timeout (Optional[float]): The amount of time, in seconds, to wait for the request to complete. Note that if ``retry`` is specified, the timeout applies to each individual attempt. metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata that is provided to the method. Returns: A :class:`~google.api_core.page_iterator.PageIterator` instance. An iterable of :class:`~google.cloud.dataproc_v1beta2.types.AutoscalingPolicy` instances. You can also iterate over the pages of the response using its `pages` property. Raises: google.api_core.exceptions.GoogleAPICallError: If the request failed for any reason. google.api_core.exceptions.RetryError: If the request failed due to a retryable error and retry attempts failed. ValueError: If the parameters are invalid.
