      Immutability crucially allows for hashability, so you can use (some) tuples as dict keys.

  array.array, as another commenter mentioned; numpy.array is popular for performance-oriented code (but not in the stdlib); collections.deque; queue.Queue; tuple; struct (though it's a bit of a pain to make one behave in an array-like way and is usually better to use array.array); heapq; and multiprocessing.shared_memory.ShareableList. Out in pypi there are many additional esoteric list-like data structures: bitarray is one of my favorites, and there's also awkward-array, cyarray, tinyarray, fixedlist, blist, bigarray, sortedcontainers, and many many more.
