WebAn array is an object of type np.ndarray. Its values or elements are stored in a data buffer, which can be thought of as a contiguous block of memory bytes. The bytes in the data … WebThere are two different types of NumPy arrays: vectors and matrices. Vectors are one-dimensional NumPy arrays, and look like this: my_vector = np.array(['this', 'is', 'a', 'vector']) Matrices are two-dimensional arrays and are created by passing a list of lists into the np.array () method. An example is below.
