The python documentations specifies that the simple queue cannot use the functionality of tracking (task_done, join). These can be used to track that every item in the queue has been processed by another process/ thread. example code:

import threading, queue

q = queue.Queue()

def worker():
    while True:
        item = q.get()
        print(f'Working on {item}')
        print(f'Finished {item}')
        q.task_done()

# turn-on the worker thread
threading.Thread(target=worker, daemon=True).start()

# send thirty task requests to the worker
for item in range(30):
    q.put(item)
print('All task requests sent\n', end='')

# block until all tasks are done
q.join()
print('All work completed')

In the above code the main thread uses join to wait for the other thread to finish processing every item it send. Meanwhile, the worker thread signals "task done" every time he handles an item in the queue. "task" is an item in the queue in this context.

Hope this helps,
