queue.LifoQueue(maxsize = 0) 即“后进先出”队列。参数同上。同样的,如果maxsize <= 0,那么maxsize无穷。 priority queue: queue.PriorityQueue(maxsize = 0) 可以创建一个优先级队列,省得排序了。 在Python 3.7.+ 版本中又引入了一个新的结构:SimpleQueue: queue.SimpleQueue() 构造一个maxsize = 0的FI...
『Last in, first out』 (LIFO) 队列允许用户首先访问最新添加的对象。 最后,优先级队列(priority queue)允许用户根据对象对应的优先级类别来检索对象。 如何使用 queue 在 Python 中实现多线程编程,示例详见:https://www.tutorialspoint.com/python3/python_multithreading.htm。 __repr__ 在Python 中定义一个类别...
