我可以从 PriorityQueue 中获取一个项目而不删除它吗?
问题描述：
我想获取队列中的下一项，但我不想让它出列.在 Python 的 queue.PriorityQueue 中是否有可能?从 docs，我没有看到怎么办
I want to get the next item in queue but I don't want to dequeue it. Is it possible in Python's queue.PriorityQueue? From the docs, I don't see how can it be done
答
当您按照理论从队列中获取项目时，它将从队列中删除.您必须编写自己的函数，该函数将为您提供 PriorityQueue 的最后一个元素.可以通过继承priorityqueue来创建peek函数.
When you get item form the queue as per theory it will remove from the queue. You have to write your own function which will give you last element of PriorityQueue. You can create a peek function by inherit the priorityqueue.
