[issue32782] memoryview & ctypes: incorrect itemsize for empty array

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

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.
