https://docs.python.org/3/library/stdtypes.html#typememoryview says "itemsize The size in bytes of each element of the memoryview" Revising the code example to use an empty array: >>> import array, struct >>> m = memoryview(array.array('H', [0]) >>> m.itemsize 2 I agree that itemsize should also be non-zero for ctype formats.
