multiprocessing.shared_memory.ShareableList can be useful in some circumstances, even if you don’t intend on sharing it across processes. It allows direct access to the data, elements are mutable (to an extent; you can’t increase the size of either the overall list or its elements once built), and since the underlying shm is exposed, you can get memoryviews for zero-copy.
The downside is they’re on the more esoteric side of Python, so people may not be as familiar with them as other structures.
