Used by Queue consumer threads. For each get() used to fetch a task, a subsequent call to task_done() tells the queue that the processing on the task is complete. If a join() is currently blocking, it will resume when all items have been processed (meaning that a task_done() call was received for every item that had been put() into the queue). Raises a ValueError if called more times than there were items placed in the queue. rz!task_done() called too many timesN)r"r# ValueError notify_all)r% unfinisheds r task_donezQueue.task_done9s] ..2JQ>$%HII##..0$.D ! ! s AAA%c|j5|jr'|jj|jr'dddy#1swYyxYw)aBlocks until all items in the Queue have been gotten and processed. The count of unfinished tasks goes up whenever an item is added to the queue. The count goes down whenever a consumer thread calls task_done() to indicate the item was retrieved and all work on it is complete. When the count of unfinished tasks drops to zero, join() unblocks.
