...)
Copy
>>> # Use the warehouse collection created before to create a reference to a warehouse resource

>>> warehouses = warehouse_collection.iter(like="your-warehouse-name")
Copy

Showing warehouses starting with ‘your-warehouse-name-‘:

>>> warehouses = warehouse_collection.iter(like="your-warehouse-name-%")
Copy

Using a for loop to retrieve information from iterator:

>>> for warehouse in warehouses:
>>>     print(warehouse.name, warehouse.warehouse_size)
Copy
