copy - how to deepcopy a queue in python

Question

Hi How to deepcopy a Queue in python? Thanks

Answer 1

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).

(It is possible to construct many deepcopy's of a Queue by .get and .put, but the original Queue will be destroyed.)

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.
