What is a the Python program you requested given the following:
Complete the below
def consume_items(queue, callback, verbose=True):

    ''''A lighter-weight version of handle_items that uses AMQP\'s
    basic.consume instead of basic.get. Callback is only passed a
    single items at a time. This is more efficient than
    handle_items when the queue is likely to be occasionally empty
    or if batching the received messages is not necessary.'
