python queue队列

queue.Queue(maxsize=0) #先入先出，maxsize限制数量

queue.LifoQueue(maxsize=0) #last in fisrt out

queue.PriorityQueue(maxsize=0) #存储数据时可设置优先级的队列

Queue.put(item, block=True, timeout=None)#放入队列

Queue.get(block=True, timeout=None)#队列取出，block为false去到0不会卡住

Queue.qsize()#判断队列大小

Queue.full() # return True if full 

Queue.empty()#如果队列空则返回真
