Python - Print a 5x5x3 numpy array as three 5x5 numpy arrays?

Question

When I print my 5x5x3 numpy array, it prints as 5 5x3 arrays.

I have read in a 5 pixel x 5 pixel rgb image and want to view the 5x5 arrays that are R, G and B. How do I do this?

Thanks!

Or for plane in np.rollaxis(matrix, -1): print(plane). Or even just print(np.rollaxis(matrix, -1)) — Eric

Something like this should work:

In [1]: import numpy as np

In [2]: a = np.array([[[1,2,3], [3,4,3]],[[5,6,3], [7,8,3]]])

In [3]: a.shape
Out[4]: (2, 2, 3)

In [4]: for i in range(a.shape[-1]):
    ...:     print(a[:,:,i])
    ...:
[[1 3]
 [5 7]]
[[2 4]
 [6 8]]
[[3 3]
 [3 3]]
