I would like to give some feedback about ...

From: http://www.checkio.org/mission/count-neighbours/solve/

I'm somewhat of a newbie when it comes to python and coding in general so please bear with me. I have a problem with the second example, When I try to run it via try it, it gives the ff output:

>>> count_neighbours(((1, 0, 0, 1, 0), (0, 1, 0, 0, 0), (0, 0, 1, 0, 1), (1, 0, 0, 0, 0), (0, 0, 1, 0, 0),), 0, 0)
<<< 1

but when I try to run my code via run and check:

AssertionError: 2nd example
 <module>, 133

It also gives me an answer of 4.

Below is my code if you need it:
