Wait for the table to be created in dynamodb to avoid Requested resource not found

How to wait for dynamodb instance table to be created before starting inserting elements?

    dynamodb = boto3.client('dynamodb', region_name="eu-west-3")
    dynamodb.create_table(
            TableName='mytable',
            KeySchema=[
                {
                    'AttributeName': 'id',
                    'KeyType': 'HASH'  # Partition key
                }
                # no sort key
            ],
            AttributeDefinitions=[
                {
                    'AttributeName': 'id',
                    'AttributeType': 'S'
                },
            ],
            BillingMode='PAY_PER_REQUEST',
        )

When I start my batch, I receive because the table is not created yet:

botocore.errorfactory.ResourceNotFoundException:
An error occurred (ResourceNotFoundException) when calling the BatchWriteItem operation:
Requested resource not found

I would like to wait for the end of the creation of the table. How to do it?

You can use this to wait for the end of the creation of the table:

waiter = dynamodb.get_waiter('table_exists')
waiter.wait(TableName='mytable')
# at this line your table is fully created and available

as described in the documentation: https://boto3.amazonaws.com/v1/documentation/api/latest/guide/clients.html#waiters
