Wrong row index in test for the "Count neighbours"

I would like to give some feedback about "count neighbours" task. I have got the error: "IndexError: tuple index out of range, count_neighbours, 12". For the test data:

сount_neighbours(
    ((1,0,1,0,1),
     (0,1,0,1,0),
     (1,0,1,0,1),
     (0,1,0,1,0),
     (1,0,1,0,1),
     (0,1,0,1,0),), **5**, 4)

But I can see wrong "row" value = "5". The 5x5 tuple has indexes from 0 to 4. Can You verify it, please?
