Here is one way you could do this:

import numpy as np

# Suppose you have a two-dimensional array
arr = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]])

# You can use np.meshgrid to generate the x and y indices
x_idx, y_idx = np.meshgrid(range(arr.shape[0]), range(arr.shape[1]))

# You can then flatten these indices and the values to get a single array
result = np.column_stack((x_idx.flatten(), y_idx.flatten(), arr.flatten()))

# This will give you the following array

np.array([[0, 0, 1],
          [1, 0, 2],
          [2, 0, 3],
          [0, 1, 4],
          [1, 1, 5],
          [2, 1, 6],
          [0, 2, 7],
          [1, 2, 8],
          [2, 2, 9]])
