Iterate over numpy with index (numpy equivalent of python enumerate)

Question

I\'m trying to create a function that will calculate the lattice distance (number of horizontal and vertical steps) between elements in a multi-dimensional numpy array. For

Answer 1

Another possible solution:

import numpy as np

A=np.array([[1,2,3],[4,5,6],[7,8,9]])
for _, val in np.ndenumerate(A):
    ind = np.argwhere(A==val)
    print val, ind

In this case you will obtain the array of indexes if value appears in array not once.
