Comparing complicated arrays.

So for example, zero in first row, column third

zero based, columns_1[3] is a 1, not 0, so assume you mean index 2 for column 3, correct?

>>> zz = '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 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 1 1 0 0 0 0 1 0 1 1 0 0 1 1 0 0 0 0 1 0 1'
>>> columns_1 = zz.split()
>>> columns_1[3]
'1'
>>>
