  The numpy function array creates a new array from any data structure with array like behavior (other ndarrays, lists, sets, etc.) Read the docs! Creating an ndarray from a list does not change the list. Often combined with a reshape() call to create a multi-dimensional array.

  NumPy operations return views or copies. Views share the underlying storage of the original array. Changing the values of a view will change the original and vice versa. Read the documentation to determine if an operation returns a copy or a view. Most operations return a view when possible and a copy otherwise.

  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
