The code that involves arrays with Numpy package is precise to apply transformations or operations for each element of the multidimensional arrays unlike a Python List. Since n-dimensional arrays of Numpy use a single datatype and contiguous memory for storage, …

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
