print a.ndim, a.shape, a.dtype 1. Arrays can have any number of dimensions, including zero (a scalar). 2. Arrays are typed. Common dtypes are: np.uint8 (byte), np.int64 (signed 64-bit integer), np.float32 (single-precision float), np.float64 (double-precision float). 3. Arrays are dense. Each element of the array exists and has the same type.
