Python queue模块的FIFO队列先进先出。 class queue.Queue(maxsize) LIFO类似于堆,即先进后出。 class queue.LifoQueue(maxsize) 还有一种是优先级队列级别越低越先出来。 class queue.PriorityQueue(maxsize) 一:FIFO先进先出 FIFO即First in First Out,先进先出。Queue提供了一个基本的FIFO容器,使用方法很简单,...
data1=(1,'python') data2=(2,'-') data3=(3,'100') style=(data2,data3,data1) foriinstyle: q.put(i)# 在队列中依次插入元素 data2、data3、data1 foriinrange(3): print(q.get())# 依次从队列中取出插入的元素,数据元素输出顺序为 data1、data2、data3 1. 2. 3. 4. 5. 6. 7....
可以看到,3个线程循环的从队列中取出元素,元素获取的顺序与放入队列的顺序一致。 示例2:LiFoQueue(后进先出队列)与PriorityQueue(优先级队列) 1importqueue23defmy_LiFo_queue():4q =queue.LifoQueue()5foriinrange(5):6q.put(i)78whilenotq.empty():9print("LiFo queue -->", q.get())1011defmy_pro...
As deque quicker append and pop operations from both ends of the queue, so it is preferred more than list in python. In place of enque and deque, there are append() and popleft() functions. In deque append and pop operations have the time complexity of O(1). Code Implementation Python ...
