In this final section, youll learn how to use the Python map() function to iterate over list items and manipulate them by applying a transformation function. Required fields are marked *. The extra power of NumPy comes from the fact that we can even control the way to visit the elements (Fortran order rather than C order, say :)) but the one caveat is that the np.nditer treats the array as read-only by default, so one must pass extra flags such as op_flags=[readwrite] for it to be able to modify elements.
