Hi ,
I had a Question,i hope i'll find the solution here.
Say i have a Queue.
h = Queue.Queue(maxsize=0) h.put(1) h.put(2) h.empty() False h.join() h.empty() False h.get() 1 h.get() 2 h.get() Blocked.......................
My Question is : In a single threaded environment why does the get() gets blocked , instead of raising an exception.On interpreter i have no way to resume working.
And my second question is : Why doe we have to explicitly call task_done after get(). why doesn't get() implicitly call task_done(). as for put() entry for unfinished_task is automatically added .why not get deleted in get() then.
The way it's used is to get a item, process it, and then signal that it has finished with it. There's going to be a period of time when an item is not in the queue, but is still being processed.
