WebNumPy package contains an iterator object numpy.nditer. It is an efficient multidimensional iterator object using which it is possible to iterate over an array. Each element of an array is visited using Python’s standard Iterator interface. Let us create a 3X4 array using arange () function and iterate over it using nditer. Example 1 WebNumPy provides an iterator object, i.e., nditer which can be used to iterate over the given array using python standard Iterator interface. Consider the following example. Example import numpy as np a = np.array ( [ [1,2,3,4], [2,4,5,6], [10,20,39,3]]) print("Printing array:") print(a); print("Iterating over the array:") for x in np.nditer (a):
