Print an integer array as hexadecimal numbers

Question

I have an array created by using

array1 = np.array([[25,  160,   154, 233],
                   [61, 244,  198,  248],
                   [227, 226, 141, 72 ]         


        

Answer 1

This one-liner should do the job:

print '[' + '],\n['.join(','.join(hex(n) for n in ar) for ar in array1) + ']'
