Clear all items from the queue

Question

How can I clear a queue. For example I have datas in a queue, but for some reason I don\'t need the existing data, and just want to clear the queue.

Is there any wa

Answer 1

You just can not clear the queue, because every put also add the unfinished_tasks member. The join method depends on this value. And all_tasks_done needs to be notified also.

q.mutex.acquire()
q.queue.clear()
q.all_tasks_done.notify_all()
q.unfinished_tasks = 0
q.mutex.release()

or in decent way, use get and task_done pair to safely clear the tasks.

while not q.empty():
    try:
        q.get(False)
    except Empty:
        continue
    q.task_done()

or just create a new Queue and delete old one.
