<div class="method">
    <code class="details" id="list">list(parent, filter=None, pageSize=None, pageToken=None, x__xgafv=None)</code>
  <pre>Lists datasets under a project. Pagination is supported.

Args:
  parent: string, Required. Dataset resource parent, format: projects/{project_id} (required)
  filter: string, Optional. Filter on dataset is not supported at this moment.
  pageSize: integer, Optional. Requested page size. Server may return fewer results than requested. Default value is 100.
  pageToken: string, Optional. A token identifying a page of results for the server to return. Typically obtained by ListDatasetsResponse.next_page_token of the previous [DataLabelingService.ListDatasets] call. Returns the first page if empty.
  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # Results of listing datasets within a project.
  &quot;datasets&quot;: [ # The list of datasets to return.
    { # Dataset is the resource to hold your data. You can request multiple labeling tasks for a dataset while each one will generate an AnnotatedDataset.

If you specify the URI of a table that already exists, it must have the [correct schema](/ml-engine/docs/continuous-evaluation/create-job#table-schema). Provide the table URI in the following format: &quot;bq://{your_project_id}/ {your_dataset_name}/{your_table_name}&quot; [Learn more](/ml-engine/docs/continuous-evaluation/create-job#table-schema).
