The primary class defined by NumPy is ndarray. The ndarray is implemented as a contiguous memory segment. Internally, all ndarray instances have a pointer to the loca-tion of the first element as well as the attributes shape, ndim, and strides. ndim describes the number of dimensions in the array, shape describes the number of elements in each

NumPy Fundamentals • Why Numpy? • Remember that Python does not limit lists to just elements of a single class • If we have a large list and we want to add a number to all of the elements, then Python will asks for each element: • What is the type of the element • Does the type support the + operation • Look up the code for the + and execute • This is slow
