You don't actually want to quit when the queue has no unfinished work, because conceptually that's not when the application should finish.
I think it does q.join() before anything is put in the queue and exits immediately. Try joining all producers before joining queue.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
