What did you expect? Since you've done only one put in the Queue, there's nothing left in it. Since queues are meant to communicate between threads - and also often to synchronize them -, the default behaviour for the get when the queue is empty is to wait for something to be put in it. If you want your second get to fail, use the get_nowait method.
