Description:
In the docstring of ex02, it states that both args and the return value should be of type numpy.ndarray. However, in ex03–ex07 and ex09, their types are specified as numpy.array instead.
Since numpy.array is a function and numpy.ndarray is a class, all occurrences of numpy.array should be corrected to numpy.ndarray.
