nUS:: a+ US: a [ S5 eU R R 5 Xl SSS5 g! , ( d f g= f)a8 Indicate that a formerly enqueued task is complete.
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).
shutdown(immediate=True) calls task_done() for each remaining item in
the queue.
Raises a ValueError if called more times than there were items
placed in the queue.

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.

This method is likely to be removed at some point. Use qsize() == 0
as a direct substitute, but be aware that either approach risks a race
condition where a queue can grow before the result of empty() or
qsize() can be used.
To create code that needs to wait for all queued tasks to be
completed, the preferred technique is to use the join() method.

By default, gets will only raise once the queue is empty. Set
'immediate' to True to make gets raise immediately instead.
All blocked callers of put() and get() will be unblocked. If
'immediate', a task is marked as done for each item remaining in
the queue, which may unblock callers of join().
