Wait for complete deletion of a DynamoDB table using boto3

I need to delete a dynamodb table, and wait until it is completely removed. How can I check this?
boto3 api expose a method get_waiter to wait for certain events, but it is not well documented. Can I use it for this purpose? Which would be the event name, or maybe handle a ResourceNotFoundException

# Wait until the table exists.
table.meta.client.get_waiter('table_exists').wait(TableName='TableName')

Answer

After delete_table API, call table_not_exists waiter. This waits until the specified table returns 404.

import boto3
client = boto3.client('dynamodb')
client.delete_table(TableName='foo')
waiter = client.get_waiter('table_not_exists')
waiter.wait(TableName='foo')
print ("table deleted")

For create_table API, call table_exists waiter. This waits until the specified table gets active.
