.. literalinclude:: ../samples/list_tables.py
   :language: python
   :dedent: 4
   :start-after: [START bigquery_list_tables]
   :end-before: [END bigquery_list_tables]

Getting a Table
^^^^^^^^^^^^^^^

Get a table resource with the

.. literalinclude:: ../samples/get_table.py
   :language: python
   :dedent: 4
   :start-after: [START bigquery_get_table]
   :end-before: [END bigquery_get_table]

Browse data rows in a table with the
:func:`~google.cloud.bigquery.client.Client.list_rows` method:
