What is the general type for ctypes.Array and np.ndarray?

[monchin]

I have a function, and one parameter of it is an array, but it could be either multiprocessing.sharedctypes.RawArray(with typing ctypes.Array) or numpy.ndarray. In my opinion, both of these could be describe as array, but I can't find a type to contain both. I tried Sequence and Iterable, neither contains RawArray. So is there any suggestions? Or the only way to solve it is Union?

A Union is very likely what you want. You could also potentially write a Protocol defining exactly what you expect the shared behaviour to be.
