如何在 python 中深度复制队列?谢谢
Hi How to deepcopy a Queue in python? Thanks
推荐答案
queue
The queue module in Python is used for synchronizing shared data between threads. It is not intended as a data structure and it doesn't support copying (not even shallow copy).
(.get和.put可以对一个Queue进行多次deepcopy，但是原来的Queue会被销毁.)
(It is possible to construct many deepcopy's of a Queue by .get and .put, but the original Queue will be destroyed.)
如果您想将队列(或堆栈)作为数据结构，使用 collections.deque.如果您想要优先级队列，请使用 heapq 模块.deque 支持 deepcopy.heapq 由列表支持，因此也支持 deepcopy.
If you want to have a queue (or stack) as a data structure, use a collections.deque. If you want a priority queue, use the heapq module. The deque supports deepcopy. heapq is backed by a list, so deepcopy is also supported.
